When I type in "^" it is highlighted and waits for the next keyboard input such that if available, the next input is accented with it. For example typing in "^" and then "a" would result in "â" instead of "^a". How do I prevent this from happening?
I was able to solve this by creating a custom layout with the help of this post
https://superuser.com/questions/665494/how-to-make-a-custom-keyboard-layout-in-os-x.
First downloaded Ukelele.
Chose my desired layout to be edited as the current layout.
In Ukelele, went to File -> New From Current Input Source
The current layout is then shown on an on-screen keyboard. All the keys that will automatically accent the next keyboard input are highlighted with a different color from the rest of the keyboard. Right Click on the highlighted key and clicked on Make Output and pressed OK.
This makes the output of the key to the character and does not accent any following inputs. Did the same for all other highlighted keys ("Dead Keys" I think they are called).
Then saved the keyboard layout as a Bundle file anywhere (Remember to also change the name of the keyboard layout within the bundle. Otherwise it will have the same name as the layout you started with and may cause confusion when trying to select it)
Moved the saved bundle to ~/Libraray/Keyboard Layouts/
Selected the new layout from the Input Sources in System Preferences
Became a happy programmer :)
If by chance you are using the US International PC layout, remove that and use US, British, or ABC instead.
In the Spanish LATAM layout I ran into the same problem with the symbols ~, ^ and `. I added comfortable key bindings for them as "regular keys" (contrary to dead keys) with Karabiner. I think the approach I followed could work with other layouts as well, although I haven't tried.
Using Karabiner-Elements
Before getting into Karabiner, select "Show Keyboard Viewer" in the menu of the Input icon in the menu bar. You should see a virtual keyboard displayed. If the Input icon is not shown, enable:
System Preferences > Keyboard > Input Sources > Show Input menu in menu bar
Leveraging the virtual keyboard, find if there is a specific key combination to make the special symbol be printed as-is (without waiting for another key press). For instance, in Spanish LATAM, pressing Option+Shift+{ directly prints ^.
The amount of keystrokes can be reduced using Karabiner. The following is an example of a complex modification to reduce Option+Shift+{ into Option+{ for typing ^ in the Spanish LATAM layout. To find the value for key_code, use Karabiner's EventViewer.
{
"title": "Regularize dead keys - Spanish LATAM",
"rules": [
{
"description": "left_option+{ PRINTS caret(^)",
"manipulators": [
{
"type": "basic",
"from": {
"key_code": "quote",
"modifiers": {
"mandatory": ["left_option"]
}
},
"to": {
"key_code": "quote",
"modifiers": ["left_option", "left_shift"]
}
}
]
}
]
}
In my case, my laptop keyboard was working fine, but somehow I bumped some keys and then my external keyboard was typing symbols instead of characters and numbers as expected.
I was going to investigate further, then I remembered the ancient wisdom that provides the simplest solution.
unplug it & plug it back in.
I have been developing in zend studio and there is a feature I miss a lot in Xcode. When you are reading code in a main function and you want to go in a specific function to read something, you can click in the left area of your current line of code were your are, and a flag-mark appears in that line of code, so you can go anywere else in the code and it will be very easy to come back to that line of code you were before because there is a flag and you only have to click on it and you automatically go back. Does Anybody know a similar way to do this in Xcode?
Unfortunately, this feature was present in earlier versions of Xcode (up to Xcode3 IIRC) and was called "Bookmarks", but it was removed since then.
You can use breakpoints (and disable them) as a workaround, even if it's not perfect. I personally prefer using other tricks, like "Open Quickly" and named tabs.
Alternate trick 1 : "Open Quickly"
One trick is to use Command+Shift+O (or "File" menu > "Open Quickly") to quickly open a file. In the field that appears, you can type:
The name or parts of the name of a file.
Typing "MainViewController" will propose to jump to the MainViewController.h or MainViewController.m file.
Typing "MainVC" will work too, as well as "MainViewCtrl", as long as the order of the letters you type is the same as the full name.
Very handy to just type "ContTVCell" to open the ContactsTableViewCell.h file that is hidden deep in subgroups of my project for example
Similarly, you may also type the name or parts of the name of a symbol, especially a method name.
For example, typing tvcellforrow will list you all the definitions of -tableView:cellForRowAtIndexPath: it could find in your project and let to jump to the one you want
When typing (parts of) the name of a file, adding : followed by a number at the end will allow you to directly jump at the corresponding line
For example, typing mvc:50 will propose you to jump to line 50 of MainViewController.h or MainViewController.m
Another trick : using (named) tabs
Don't forget that you can open tabs in Xcode, which can be very handy in this kind of situation.
When you are editing a file at some interesting position, you can create a new tab to browse elsewhere and go at any other place… and then go back to your first tab to find the code where you left it at the time you switched to the other tab.
Don't forget that you can name your tabs (simply double-click on their title) to give them a more explicit title. You may then quite think of them as "named bookmarks" somehow
Likewise, don't forget that you can detach tabs in separate windows too, if you prefer (for example to keep them around and visible on your secondary screen while you edit another part of your code)
You can even combine this with the "Open Quickly" trick presented above: once you made the "Open Quickly" field appear and typed something into it, instead of just validating using the enter key:
use Alt+Shift+enter to let Xcode present you a small widget that let you choose where you want the file to open (in the current tab, in another tab, in the assistant editor, in a dedicated window…)
use Alt+enter to open the file using the alternate navigation defined in Xcode preferences (Xcode > Preferences > Navigation > Optional Navigation). By default, the behavior when opening a file while using the Alt key is to open the file in the Assistant Editor. Personally I changed that in my Xcode preferences as I prefer to make Xcode open the file in a separate tab instead, which makes Alt+clic much more useful.
Sure, all those tricks with "Open Quickly…" and "Tabs" do not replace the bookmarks feature that you are missing. But they are still nice alternate ways to jump quickly to any position in your code, even any specific line of any specific file in your project, wherever you are in Xcode (even without having to have the Project Navigator visible on the left part of your window), and let you have multiple editors in different tabs to go quickly back to a part of interest in your code
its on top of your editor i have added two pics just check them.
When you navigate to another place in Xcode, say, open a different file, or Command-click and jump to definition, you can go forward and back by swiping right or left on the trackpad with two fingers.
You can also use keyboard shortcuts: Ctrl+⌘+→ to go forward, or Ctrl+⌘+← to go back.
Finally, you can click triangular buttons at the top left in your edit area.
There is a go back button at the top left of the editor!
If that is not good enough, whar I do is misuse breakpoints to set flags in my code. The breakpoint navigator thus becomes a table of flags. It isn't much but there you are.
In Xcode < 4, you could hold the "option" key, and the "Replace All" button would change to "Replace in Selection". As of Xcode 4, this does nothing. Anyone know if there's a new way to do it, or is it bug filing time?
This appears to be working again now, at least in Xcode 4.4.1.
When the find/replace bar appears at the top of the editor, holding down the option key on the keyboard causes "Replace in Selection" to appear in lieu of "Replace All."
I'm glad, because this was an ANNOYING omission.
Another workaround:
In Xcode, select the text, press copy
In a terminal session:
pbpaste|sed 's/SOURCETEXT/NEWTEXT/g'|pbcopy
Return to Xcode window, press paste
Since the original should still be selected, it will just be replaced. You could probably build a simple shell script to do this.

Find/Replace in Xcode using Regular Expressions
Seems like missing functionality. You should file a bug report.
I'm upset that they took out this functionality, as I used it constantly, but here's my workaround. Copy your selected text from Xcode4 to TextEdit or some other word processor, do the find and replace there, and then copy the results back into Xcode.
It's not sexy but it's worth it if you do a lot of these "find and replace on my selection", and you leave the word processor open in Spaces as you work.
They should add "my selection" as an alternative to "workspace" and "my scope".
There is another way only replace the matches you find, rather than just this one or all of them.
I suggest you save a copy first, just in case....
In Find and Replace, Show Find Options (you can do this by pressing the magnifying glass).
Press Preview.
Uncheck all the ones you don't want replacing.
Press Replace
Hope that helps, it did me.
Not ideal, but not too bad:
Do a find and replace in workspace (cmd-opt-shift-f) enter your desired find/replace
Enter your desired search term and hit return
Select the range of replacements from the list of matches on the left
Hit replace (not replace all)
To replace text in a selection using Xcode 9
Press Option-Command-F to bring up the find/replace box.
Enter the search and replace string. Changing the search string will lose any existing selection, so..
Make your selection (again). (If you don't do this, the selection will be the first search string found only)
Hold down the key and "Replace All" will change to "Replace Selection", then click it.
Once you understand that you make your selection AFTER you have entered the search string, then this is not that clumbersome and works fine.
I find alt-command-f easier for local find and replace (4.3) and then working around your selection.
EthenA.Wilson asked in a comment to the OP a couple of days ago:
"Is there a way to do this in Xcode 5?"
For the benefit of those who, like me, had been searching for it, here's how:
After you put your Find and Replace terms in the bars at the top left-hand side of the editor page, select the text you want to search in, then look at the top right-hand side (same bar). You'll see where it says "All", right next to "Replace." Now press the Option key. "All" will change to "All in Selection." Click it, and you're done. Could be a bit more intuitive, but the functionality is there in Xcode 5.
Naturally, good idea to take a snapshot before you click!
HTH!
Not sure which feature prior to Xcode 4 you're referring to, but the shortcut Command+Shift+E gives you "Use Selection for Replace". If you're talking about "Find and Replace in Workspace" (Command+Option+Shift+F), then what you need to do is run your find and then hold down "Shift" or "Command" on the selections shown and then hit "Replace".
I'm writing this question because one little invisible problem has taken from me hours and hours of dummy searchings, and the time just has been wasted (here is that question: CSS: Is there any difference between these two parts?)
Does anybody know how the character 0x08 ("backspace" in ASCII) can be written into a text using a MacBook and a simple IDE (I use the "Coda")?
There is no ability to press Alt + 08 on MacBook (there is no digital keys part on the MacBook's keyboard).
How it can happen?
Did you copy & paste it from anywhere? Because the only way I know - apart from what SCFrench suggested - is to enable this in Terminal by typing:
stty erase SPACE CTRL+V CTRL+H RETURN
Not sure if this is the easiest way, but:
In the Keyboard system preferences panel, check "Show Keyboard & Character Viewer in menu bar".
Find the Keyboard menu bar icon (on the right side of the menu bar), click it, and select "Show Character Viewer".
In the Characters window that appears, find the "View" pop up menu and select "Code Tables".
Select the Unicode coding tab.
In the middle section where all the characters are displayed, click on the entry for 0008 (it will be blank, but the Name: field will say "BACKSPACE").
Click the Insert button in the same window.
Since the character is non-printable, it doesn't actually show anything in the text editor, but (at least in TextEdit) you will see that you have to hit the left or right arrow key more than once to move past it. I also confirmed by dumping the file in hex that it contains a 08 byte.
You could also use this technique to set up a Text Substitution in the Text tab of the Language & Text system preference panel.
Shift + Up Arrow + Delete/Backspace. It's a bug.

I know the combination Ctrl+A to jump to the beginning of the current command, and Ctrl+E to jump to the end.
But is there any way to jump word by word, like Alt+←/→ in Cocoa applications does?
Out of the box you can use the quite bizarre Esc+F to move to the beginning of the next word and Esc+B to move to the beginning of the current word.
On macOS (all versions) the following keyboard shortcuts work by default.
ALT+F to jump Forward by a word.
ALT+B to jump Backward by a word.
Note that you have to make set the Option key to act like the Meta key. You can do this in Terminal by accessing preferences (CMD+,) and selecting Profiles -> Keyboard. In iTerm2 Pselect rofiles -> Keys -> General and select "Option key as Esc+."
Additionally some Emacs-style key bindings for simple text navigation seem to work on bash shells. You can use:
CTRL+F to move forward by a char
CTRL+B to move backward by a char
CTRL+A to jump to start of the line
CTRL+E to jump to end of the line
CTRL+K to kill the line starting from the cursor position
ALT+D to delete a word starting from the current cursor position
CTRL+W to remove the word backwards from cursor position
CTRL+Y to paste text from the kill buffer
CTRL+R to reverse search for commands you typed in the past from your history.
CTRL+S to forward search (works in ZSH for me but not bash)
Here's how you can do it
By default, the Terminal has these shortcuts to move (left and right) word-by-word:
esc+B (left)
esc+F (right)
You can configure alt+← and → to generate those sequences for you:
Open Terminal preferences (cmd+,);
At Settings tab, select Keyboard and double-click ⌥ ← if it's there, or add it if it's not.
Set the modifier as desired, and type the shortcut key in the box: esc+B, generating the text \033b (you can't type this text manually).
Repeat for word-right (esc+F becomes \033f)
Alternatively, you can refer to this blog post over at textmate:

Switch to iTerm2. It's free and much nicer than plain old terminal. Also it has a lot more options for customization, like keyboard shortcuts.
Also I love that you can use cmd and 1-9 to switch between tabs. Try it and you will never go back to regular terminal :)
How to set up custom keyboard preferences in iterm2
Install iTerm2
Launch and then go to preference pane.
Choose the keyboard profiles tab
You will either need to copy the profile to something new and then delete the arrow key shortcuts such as ^+ Right/Left or if you don't care about a backup just delete them from the default profile.
Next make sure your modified profile is selected (starred)
Now choose the keyboard tab (very top row)
Click on the plus button to add a new keyboard shortcut
In the first box type CMD+Left arrow
In the second box choose "send escape code"
In the third box type the letter B
Repeat with desired key combinations. escape+B moves one word to the left, escape+f moves one word to the right.
you may also wish to set up cmd+d to delete the word in front of the cursor with escape+d
I often hit the wrong button (cmd / control / alt) with an arrow key and so i have my arrow key combinations with those buttons all set to jump forward and back words, but please do what fits you best.
Actually there is a much better approach. Hold option ( alt on some keyboards) and press the arrow keys left or right to move by word. Simple as that.
option←
option→
Also ctrle will take you to the end of the line and ctrla will take you to the start.
I have Alt+←/→ working: open Preferences » Settings » Keyboard, set the entry for option cursor left to send string to shell: \033b, and set option cursor right to send string to shell: \033f. You can also use this for other Control key combinations.
Use Natural Text Editing preset!
Essentially it binds, among other key sequences, Option + LeftArrow to ^[b sequence and Option + RightArrow to ^[f
This works in fish and bash, as well as in psql terminal.
Actually it depends on what shell you use, however most shells have similar bindings. The bindings you are referring to (e.g. Ctrl+A and Ctrl+E) are bindings you will find in many other programs and they are used for ages, BTW also work in most UI apps.
Here's a look of default bindings for Bash:
Most Important Bash Keyboard Shortcuts
Please also note that you can customize them. You need to create a file, name as you wish, I named mine .bash_key_bindings and put it into my home directory. There you can set some general bash options and you can also set key bindings. To make sure they are applied, you need to modify a file named ".bashrc" that bash reads in upon start-up (you must create it, if it does not exist) and make the following call there:
bind -f ~/.bash_key_bindings
~ means home directory in bash, as stated above, you can name the file as you like and also place it where you like as long as you feed the right path+name to bind.
Let me show you some excerpts of my .bash_key_bindings file:
set meta-flag on
set input-meta on
set output-meta on
set convert-meta off
set show-all-if-ambiguous on
set bell-style none
set print-completions-horizontally off
These just set a couple of options (e.g. disable the bell; this can be all looked up on the bash webpage).
"A": self-insert
"B": self-insert
"C": self-insert
"D": self-insert
"E": self-insert
"F": self-insert
"G": self-insert
"H": self-insert
"I": self-insert
"J": self-insert
These make sure that the characters alone just do nothing but making sure the character is "typed" (they insert themselves on the shell).
"\C-dW": kill-word
"\C-dL": kill-line
"\C-dw": backward-kill-word
"\C-dl": backward-kill-line
"\C-da": kill-line
This is quite interesting. If I hit Ctrl+D alone (I selected d for delete), nothing happens. But if I then type a lower case w, the word to the left of the cursor is deleted. If I type an upper case, however, the word to the right of the cursor is killed. Same goes for l and L regarding the whole line starting from the cursor. If I type an "a", the whole line is actually deleted (everything before and after the cursor).
I placed jumping one word forward on Ctrl+F and one word backward on Ctrl+B
"\C-f": forward-word
"\C-b": backward-word
As you can see, you can make a shortcut, that leads to an action immediately, or you can make one, that just inits a character sequence and then you have to type one (or more) characters to cause an action to take place as shown in the example further above.
So if you are not happy with the default bindings, feel free to customize them as you like. Here's a link to the bash manual for more information.
Hold down the Option key and click where you'd like the cursor to move
If you happen to be a Vim user, you could try bash's vim mode. Run this or put it in your ~/.bashrc file:
set -o vi
By default you're in insert mode; hit escape and you can move around just like you can in normal-mode Vim, so movement by word is w or b, and the usual movement keys also work.
If you check Use option as meta key in the keyboard tab of the preferences, then the default emacs style commands for forward- and backward-word and ⌥F (Alt+F) and ⌥B (Alt+B) respectively.
I'd recommend reading From Bash to Z-Shell. If you want to increase your bash/zsh prowess!
As of Mac OS X Lion 10.7, Terminal maps Option-Left/Right Arrow to Esc-b/f by default, so this is now built-in for bash and other programs that use these emacs-compatible keybindings.
In Bash, these are bound to Esc-B and Esc-F.
Bash has many, many more keyboard shortcuts; have a look at the output of bind -p to see what they are.
Under iterm2's Preferences > Profile > Keys, you click the + below Key Mappings and record a new shortcut. For Action, select Send Escape Sequence and type b or f for backwards and forwards respectively.
When I tried to record one for (Ctrl+←), I noticed in the Keyboard Shortcut field that the arrow never showed up. Turns out I had to disable the default mac's System Preferences > Keyboard > Shortcuts > Mission Control shorcuts first to get things to work, as they'll override iterm2's default shortcuts. Should be true for the standard terminal app, too.
For some reason, my terminal's option+arrow weren't working. To fix this on macOS 10.15.6, I opened the terminal app's preferences, and had to set the bindings.
Option-left = \033b
Option-right = \033e
For some reason, the option-right I had was set up to be \033f. Now that it's fixed, I can freely skip around words in the termianl again.
Here's the CLI way to do so, verified it works on bash.
Add the following to your ~/.inputrc:
# macOS Option + Left/Right arrow keys to move the cursor wordwise
"\e\e[C": forward-word
"\e\e[D": backward-word
The advantage of this method is that it is terminal application agnostic - doesn't matter whether you use Terminal.app, iTerm2, or any other application.
Inspiration got from this other answer.
New answer for iTerm2 Build 3.3.4 users:
Step 1: (macOS X) System Preferences > Keyboard > Shortcuts tab > Select Mission Control (left panel) > Uncheck shortcuts that labeled as "Move left a space" and "Move right a space"
Step 2: (iTerm2 Build 3.3.4) Preferences > Profiles > Select * Default (left panel) > Keys tab > Delete both "⌥->" and "⌥<-" entries > Set both "Left Option (⌥) Key:" and "Right Option (⌥) Key:" to Esc+
No messing around with shell profiles, no messing around with inferior masOS (default) Terminal, no awkwards Esc+F/B, rinse & repeat non-sense.
Done deal!!!
Enjoy this tip, my fellow PROGRAMMERS!
As answered previously, you can add set -o vi in your ~/.bashrc to use vi/vim key bindings, or else you can add following part in .bashrc to move with Ctrl and arrow keys:
# bindings to move 1 word left/right with ctrl+left/right in terminal, just some apple stuff!
bind '"\e[5C": forward-word'
bind '"\e[5D": backward-word'
# bindings to move 1 word left/right with ctrl+left/right in iTerm2, just some apple stuff!
bind '"\e[1;5C": forward-word'
bind '"\e[1;5D": backward-word'
To start effect of these lines of code, either source ~/.bashrc or start a new terminal session.
Just check the "Use Option as meta key" option in Terminal > Preferences > Settings > [profile] > Keyboard, as mentioned here already by #cris-page.
Note however, that in macOS Catalina (10.15) and newer, zsh becomes the default shell for newly added users: its default configuration considers only whitespaces as word-boundaries, whereas the old bash makes meta-left/right jump to the nearest non-alphanumerical character (similar to B/W as opposed to b/w for those familiar with vim):
v----v- bash jumps here
$ vim some-folder/what.txt_<- jump left twice from here
^---^- zsh jumps here by default
(similar motions are true for meta-backspace as well)
There are more than one ways to make zsh command line editor navigation work similarly to bash's - here is one such method:
# Place in your profile init script, e.g. `~/.zshrc`
autoload -U select-word-style
select-word-style bash
