When I do a multiple selection from, say, the find dialog (Alt-Enter), I sometimes find that many of the selected bits are off screen, but I'd like to check the context of all of them before I start doing a multiple edit.
Is there a way to, say, cycle through them in the view (without disrupting the selections)?
Probably the easiest way is to not do a "Find All", but instead highlight (or do a single Find) what you're looking for, then use ⌘D on OS X/CtrlD on Win/Lin to sequentially add the next matches. If you come to a match you don't want to select, just use ⌘K,⌘D (or CtrlK,CtrlD) to skip the current instance and go on to the next one. ⌘U (CtrlU) is "soft undo", it moves back to the previous selection in case you made a mistake.
Alternatively, I use a color scheme with a very bright selection color (it's bright blue surrounded by bright green) so that selected regions are very easy to identify. This way I can just glance at the minimap and see where selections are, and scroll through my file quickly to ensure everything looks good. If you find a selection you don't want, you can deselect it with Alt+middle mouse button on Win/Lin, or by ⌘Shift+click on OS X. You may need to set "drag_text": false in your Preferences for it to work, though (I'm not on my Mac at the moment to test).
I've found a working solution, but it's not ideal and only works if you're ok with losing the selections (eg: with multiple selections, hit Right Arrow - you've still got multiple cursors, but the selections are gone).
It goes like this:
Make sure there is no code folding - it appears to interfere with this sort of manipulation of multiple selections.
Use altEnter in the search dialogue to select all occurrences of your regex.
Scroll through the selections until you find one you don't want (MattDMo's Neon plugin is helpful here).
Use a cursor movement to lose the selections (multiple cursors remain).
Use Alt+Left Click on the undesired cursor.
Repeat 5. as required. Making another (multiple) selection can be helpful here to locate the other cursors (eg: Control/CommandShiftLeft Arrow)
If you remove a cursor by mistake, or need to add one, use Control/Command+Left Click

there is this annoying behavior in emacs which I don't know how to get rid of it.
lets say the current cursor position is on line 10 column 15.
now I need to quickly look up something far down the same buffer, I scroll down to that location and as I scroll down (or up) the cursor keeps moving and it loses its original location.
many people suggest to set a marker before scrolling but that is not a good solution, because you have to be always mindful of this fact before scrolling (which is impossible)
I know there should be a simple solution but I have not found it yet.
I'll appreciate your suggestions
As far as I know, Emacs doesn't allow you to scroll in such a way that your point disappears. I just took a quick look at xdisp.c and it looks like this is a fundamental assumption in the C code. This is different from some more recent editors (Sublime Text, VSCode etc).
However, the "many people" you mention actually have a reasonable point. If you're moving through the file by searching (C-s the-thing-im-looking-for) then Emacs will set a marker for you automatically.
I guess you could try adding a hook that set a marker at point whenever you scrolled? It wouldn't be trivial because you'd have to cope with things like not setting a load of markers through the file as your scroll dragged the cursor down. But my recommendation is probably to alter your workflow to match how Emacs wants to do things. In this case, it's probably a better approach than the modern editors it sounds like you're used to.
An option that might or might not be useful is scroll-preserve-screen-position. The description is somewhat hard to understand, but a net result is that if you mainly scroll using C-v/M-v, the point will visually stay at the same place on the screen (so if you do e.g. C-v C-v M-v M-v, the point will come back to its original position.
However, note that many commands do push a mark before they jump: isearch, end-of-buffer, imenu, xref-find-definition ... In all those cases, you can then press C-u C-SPC (the same command that you use to set the mark but called with a prefix argument) to pop the mark (concretely, jump to the last mark). If you need to jump back more than once, you can set the variable set-mark-command-repeat-pop to t, so that you only need to do C-u once and then repeatedly press C-SPC to pop more and more marks from the mark ring.
In general, there are better ways to navigate a buffer than scrolling in the wild; the cases where you do need to scroll, starting from "your current" point are (or should/could be ...) sufficiently rare that you know beforehand that you will be spending a possibly long time "looking around" in the buffer. It is then quite fast to set a mark, do your stuff somewhere else, and C-u <mash C-SPC as often as needed> until you get back to your initial point.
I installed DataGrip and spent a couple hours getting rid of bells and whistles that distract me from editing sql, like the lightbulb. I'm down to this one that for my life I can't figure, so when I move around with the caret, the editor comes up with what it thinks is the current statement and draws a thin border around it, say if it's a line ending in a semicolon, it will border just that line, but if I have several statements each not ending in semicolon, it will think they all make up a single one and draw the rectangle around the whole thing. This in itself is distracting, plus if I hit Enter within the border, it will indent differently according to what it thinks the whole thing is. I just want Enter to go to a new line at the 0, leftmost position.
Is there any way to turn the whole feature off completely?
Apart from that, does anyone know if it's possible to get DataGrip to display the number of rows affected after an INSERT or UPDATE, like most other tools do?
I'm using it with Postgresql. Thank you in advance!
cpp_developer! (By the way, what do you think about CLion? :)
There are several questions in one, let's get answers one by one.
Lightbulb: there is no UI for getting rid of it, but there is the way. It is described in this ticket: https://youtrack.jetbrains.com/issue/IDEA-94381
TLDR:
Following line should be added to the
$IDE_CONFIG_HOME/options/editor.xml then:
<option name="SHOW_INTENTION_BULB" value="false" />
Line showing the current statement.
It can be removed, like any other color/font thing: A small helpful action. For now it is only present in the Find Action menu (Ctrl/Cmd+Shift+A), but as usual, you can assign any shortcut to it.
This action will navigate you to the settings which are relevant to the context under the caret. If there are several of them, just choose one. In your case "Statement to execute". Then remove it or make white.
Smart indenting. Just turn this off:
Number of INSERTed and UPDATEd rows can be found in Output tab. But please, run them in batch mode -> context menu "Run %your_console%.sql"
when selecting large swaths of text from webpage I have to keep left mouse button pressed while searching for the selection's end. It would be nice if the browser would "remember" selection's start point and let me search for the ending point, e.g. by dragging the scrollbar downwards, without pressing the mouse button.
Does a plugin or other implementation of this sort already exist?
The answer to this is OS/Windowing system specific. In most/all systems there is a normal way to have the system perform what you are desiring. An add-on for Firefox is not required.
Windows:
If you click (button down and up, not button down and hold) at the start, or the end of the selection you desire then move the mouse to the other end of the desired selection (scrolling the page as needed to get the the other end) you can then hold the shift key down and click again. This will select the entire region from the first point you clicked to the second point you clicked while holding the shift key. You can adjust the selection by continuing to hold the shift key while doing any of: clicking on a different location, performing a click-drag movement, or using the keyboard cursor keys. This adjustment does not change the point at which you first clicked, just the second, end point.
It is also possible to use the control key to select individual items. This is possible in combination with clicks, double-clicks, and triple-clicks. An example would be to move your mouse around in this paragraph holding the ctrl key down while double-clicking on various words. Your selection will include just the words on which you double-clicked. In some instances, when using only a single ctrl-click to select from a discrete list (e.g. a Windows Explorer folder display), a second ctrl-click on the same item will de-select it. You can also combine the use of ctrl-click and shift-click to create more complex selections with the beginning of the shift-click selection starting at the most recent ctrl-click location.
The Mouse and Pointers page in the Windows Dev Center provides some fairly technical descriptions as guidelines for Windows developers.
Linux (using GNOME):
The interactions are similar to What was described for Windows, but a bit different. Section 10.1.2. Selecting Objects of the GNOME Human Interface Guidelines 2.2.3 provides a good description.
Apple/OSX:
The Macintosh Human Interface Guidelines describes how selections can be made on Apple machines.
Okay, I'll bite.
I've got really pleasant code/window colors set up in Xcode. Ordinarily, my selection color is very visible.
When I am doing a project search and iterating through the results, however, the results list stays in focus and the found text remains out of focus, using a different background color. This color is extremely hard to detect, especially when the text is embedded in a larger code block and the view is shifting around as it scrolls to the results.
Here's an example:
Left side is in focus (just normal selection), right side is out of focus (during project find)
Often it takes a few seconds to find where the heck the selected text is.
Unless I'm just missing it, Xcode seems to offer no way to change this particular selection color. Interestingly, it also doesn't seem to follow the selection color from the Appearance panel.
Does anyone know a way to change this color or force it to be more visible, short of changing my entire color scheme around?
Use this Xcode plugin:
http://github.com/tjw/XcodeSelectionColorFix
Instructions for using it are here: http://github.com/tjw/XcodeSelectionColorFix/blob/master/README.markdown
You can manually edit the theme file, which might allow a different selection color. If I recall (not on my dev machine), personal themes are in ~/Library/Application Support/Xcode/(should be intuitive from here/can't remember)
You can edit them in Property List Editor, if I remember right. The Xcode preferences don't expose all of the options available in the theme file.
Often, when I am reading code or debugging, I want the ability to quickly jump around files. I especially want to "go back" to where I was. I know about "Command+T", "Command+Shift+T", and, bookmarks. But, I cannot figure out a way to jump around files quickly.
UPDATE: I do not think I my question was clear enough judging by two answers given. Specifically, I am looking for a way to "jump back" to where I was in a file. I know how to navigate in TextMate (in general). I want to know if TextMate has a "jump back" key binding.
It's subtle.
The command-T thing has the files listed in Most Recently Used order.
So, you can go command-T return to get back to your last file real quick. At first I couldn't find it either.
I don't think there's a go to last edit location as there is in, say, IDEA/RubyMine.

2.3 Moving Between Files (With Grace)
When working with projects there are a few ways to move between the open files.
The most straightforward way is by clicking on the file tab you need. This can also be done from the keyboard by pressing ⌘1-9, which will switch to file tab 1-9.
You can also use ⌥⌘← and ⌥⌘→ to select the file tab to the left or right of the current one.
It is possible to re-arrange the file tabs by using the mouse to drag-sort them (click and hold the mouse button on a tab and then drag it to the new location). This should make it possible to arrange them so that keyboard switching is more natural.
One more key is ⌥⌘↑ which cycles through text files with the same base name as the current file. This is mainly useful when working with languages which have an interface file (header) and implementation file (source).
When you want to move to a file which is not open you can use the Go to File… action in the Navigation menu (bound to ⌘T). This opens a window like the one shown below.
Go To File
This window lists all text files in the project sorted by last use, which means pressing return will open (or go to) the last file you worked on. So using it this way makes for easy switching to the most recently used file.
You can enter a filter string to narrow down the number of files shown. This filter string is matched against the filenames as an abbreviation and the files are sorted according to how well they match the given abbreviation. For example in the picture above the filter string is otv and TextMate determines that OakTextView.h is the best match for that (by placing it at the top).
The file I want is OakTextView.mm which ranks as #2. But since I have already corrected it in the past, TextMate has learned that this is the match that should go together with the otv filter string, i.e. it is adaptive and learns from your usage patterns.
If you have a project window open, you can leave frequently-accessed files open (in tabs), and then use ⌘+1-9 to jump to open tabs.
