What are the best code blocks short cuts ? Also is there some way we can directly indent all our code ? In addition how can we move through the active tabs in codeblocks ?
Tips about tab identation are helpful when you write your code from begining. But if you paste code in CodeBlocks from some external source, like PDF document, that code often will not have good identation.
In this case, you need to select code, right click on it, and choose Format use AStyle option.
This is a plugin for CodeBlocks for right text formatting.
I hope this will help someone!
You (these are the default settings I believe) can select a block of code and press the Tab key. This will indent the entire block.
So for indenting a whole file: Ctrl + A, then Tab.
In addition, you can use Shift + Tab on a selected block to "unindent"
You can move through the open tabs with Ctrl + Shift + Tab.
As for the best shortcuts:
I like Ctrl + D to duplicate a line and
Ctrl + L to copy it.
Anyway, you can set whatever shortkeys you like in the Editor menu (there you will also be able to find all shortkey currently set).

Add shortcut as you wish from Settings->Editor->Keyboard shortcuts->plugins->Source code formatters(Astyle) or use Plugins->Source code formatters(Astyle)
CTRL+A to select the code and TAB for alignment.
I have not had much luck with the code formatter in C::B. I like my code to look like this...
if (blah..) {
SomeCode();
} else {
DifferentCode();
}
it allows more code to fit on a screen, and is still reasonably readable.
After trying to tweak the settings in Settings->Editor, then Source Formatter tab, when I went to format my code, it removed the if line entirely, and I have not been able to unset my tweaks to make it work.
Fornatually, ctrl-z still works.
The code formatter should never remove code, only play with white space.
Maybe there is a better plugin.
Mark.
In addition in How to switch between tabs in codeblocks.
codebocks 20.03
Linux (KDE Neon)
To switch between tabs.
Activate this with CTRL+SHIFT+TAB, then you can use the know options:
CTRL+TAB , to switch to the right tab.
CTRL+SHIFT+TAB , to switch to the left tab.
Or this other option, but this is not in the keyboard shortcuts, this option doesn't work in a cycle mode, when your get the last right tab, it jump to the bottom tabs:
CTRL+ right-arrow-key , to switch to the right tab.
CTRL+ left-arrow-key , to switch to the left tab.
Remember to activate with CTRL+SHIFT+TAB.
After you land in the desire tab you can type TAB to begin to start writing code.
There is a command in Visual Studio 2005 called Edit.SelectToLastGoBack (bound to Ctrl + =).
I presume it is supposed to select all the text between the current cursor position and the last 'Go Back' point, but I can't work out the algorithm it's using for deciding what that point is.
Does anyone know how to use this potentially very useful command?
Selects to the last juimp point ...
Try using the navigation bar to jump to another method in class. Then press Ctrl + "="
It will select from the start of method you jumped to all the way back to where you jumped from.
I have yet to find a use for it though TBH,
Kindness,
Dan
I use it for recording macros.
Frequently I want to select everything from this brace to that brace and cut it in a macro. Go to the first brace, hit ctrl-f (ctrl-i doesn't work right in macros), search to the second brace, close search with escape, and hit ctrl-= to get everything between the braces selected. This is much more reliably repeatable in a macro than something like using ctrl arrows to navigate a word at a time while holding down shift, and is similar to the emacs concept of setting a mark point.
I'm not sure what all starts a new 'location in navigation history', but I'm sure starting a search does and that's all I need.
I just discovered this command is available in Visual Studio 2012. I've been looking for it ever since I got VS 2012. I kept thinking it was something like anchor, like select everything between the anchor and point. I was disappointed that macro recording and playing are no longer available. But I am glad this command still exists.
Another useful command is ctrl+k ctrl+a, which is Edit.SwapAnchor. So, you could be someplace in the code, then do a find. Now you have the point and anchor (maybe also known as the cursor and last goback). You can do ctrl+= to select, then ctrl+k ctrl+a then extend from the other end using another find--or something like that.
I'm using Notepad++ as an editor to write programs in Python. It might sound daft but I looked around in the editor and could not find any means (not the manual way but something like in Emacs) to do a block comment in my code.
Since so many language settings are supported in Notepad++, I'm curious to find a way to block comment code.
CTRL+Q Block comment/uncomment.
See Keyboard And Mouse Shortcuts - Notepad++ Wiki.
Try the following shortcut:
Ctrl+K.
This link was exactly what I was searching for .
Let me summarize the answers for others' benefit (for python and notepad++)
1) Ctrl+K on multiple lines (i.e. selected region) allows you to block comment.
Also note that pressing the combination multiple times allows you to add multiple "#"s (sometimes I use that while testing to differentiate from other comments)
2) Ctrl+Shift+K (on the commented region) allows you to perform block uncomment
3) Ctrl+Shift+K on an uncommented selected region does not comment it
4) Ctrl+Q allows you to block comment/uncomment in a toggled mode (meaning, you cannot add multiple '#'s like in 1) )
Hope this helps another wandering soul.
Question - how would you develop a hack of keyboard combinations to comment/uncomment if there were no shortcuts? Just curious. I've no clue hence asking.
Yes in Notepad++ you can do that!
Some hotkeys regarding comments:
Ctrl+Q Toggle block comment
Ctrl+K Block comment
Ctrl+Shift+K Block uncomment
Ctrl+Shift+Q Stream comment
Source: shortcutworld.com from the Comment / uncomment section.
On the link you will find many other useful shortcuts too.
for .sql files Ctrl+K or Ctrl+Q does not work.
to insert comments in .sql files in Notepad++ try Ctrl+Shift+Q
(there is no shortcut to uncomment the code block though. I have tried that on v5.8.2 )
Use shortcut: Ctrl+Q.
You can customize in Settings
In your n++ editor, you can go to
Setting > Shortcut mapper
and find all shortcut information as well as you can edit them :)
Two ways for block commenting:
Ctrl+Shift+Q
or
Select the block
Alt + Right click
Choose block comment.
Without having selected a language type for your file there are no styles defined. Comment and block comment are language specific style preferences. If that's a PITA...
To select for multi-line editing you can use
shift + alt + down arrow
To add a comment under any code on NOTEPAD++ first we have to save and define the programming or scripting file type. Like, save the file as xml, html etc. Once the file is saved in proper format you will be able to add a comment directly using the shortcut ctrl+Q
Just select the desired line and click on Ctrl + Q
Ps: I am using Notepad++
I find that I am cutting and pasting a LOT when I program. For example, method, variable and class names are things I regularly cut/paste. I do use "ctrl+space" after typing part of a word to autocomplete them or popup intellisense when there's duplicates found.
But just for straight copy/pasting do you guys have any good shortcuts/tricks/tips to use?
I already use these shortcuts as I program but I wonder if I am missing anything?
ctrl+x (with nothing selected)
ctrl+v (with nothing selected)
ctrl+l (with nothing selected)
ctrl+shift+arrowKeys
If I could copy/paste quicker I think I'd be able to write code quite a bit faster.
In Visual Studio has multi-paste.
pressing Ctrl+Shift+V allows you to paste any of the 10 last things you cut/copied.
Install and learn ViEmu.
I have more of a hardware solution. On my MS 4000 keyboard I have the back and forward buttons right under the space bar bound to copy and paste respectively. This actually makes copying and pasting much easier than I thought it would when I first did it.
I use ClipX, which gives you system-wide multi-paste. You can paste any of the last [configurable number] of things in your clipboard. You can also save "favourite" items, which stick on the list forever.
Shift + Page Up/Down to select everything below/above the cursor.
If you're not using ctrl+shift+arrow to select whole words/lines, then that can help a lot.
Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
Visual Studio is such a massively big product that even after years of working with it I sometimes stumble upon a new/better way to do things or things I didn't even know were possible.
For instance-
Crtl + R, Ctrl + W to show white spaces. Essential for editing Python build scripts.
Under "HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\Text Editor"
Create a String called Guides with the value "RGB(255,0,0), 80" to have a red line at column 80 in the text editor.
What other hidden features have you stumbled upon?
Make a selection with ALT pressed - selects a square of text instead of whole lines.
Tracepoints!
Put a breakpoint on a line of code. Bring up the Breakpoints Window and right click on the new breakpoint. Select 'When Hit...'. By ticking the 'Print a message' check box Visual Studio will print out a message to the Debug Output every time the line of code is executed, rather than (or as well as) breaking on it. You can also get it to execute a macro as it passes the line.
You can drag code to the ToolBox. Try it!
Click an identifier (class name, variable, etc) then hit F12 for "Go To Definition". I'm always amazed how many people I watch code use the slower right-click -> "Go To Definition" method.
EDIT: Then you can use Ctrl+- to jump back to where you were.
CTRL+SHIFT+V will cycle through your clipboard, Visual Studio keeps a history of copies.
Sara Ford covers lots of lovely tips: http://blogs.msdn.com/saraford/archive/tags/Visual+Studio+2008+Tip+of+the+Day/default.aspx
But some of my favourites are Code Snippets, Ctrl + . to add a using <Namespace> or generate a method stub.
I can't live without that.
Check out a great list in the Visual Studio 2008 C# Keybinding poster: http://www.microsoft.com/downloadS/details.aspx?familyid=E5F902A8-5BB5-4CC6-907E-472809749973&displaylang=en
CTRL-K, CTRL-D
Reformat Document!
This is under the VB keybindings, not sure about C#
How many times do you debug an array in a quickwatch or a watch window and only have visual studio show you the first element? Add ",N" to the end of the definition to make studio show you the next N items as well. IE "this->m_myArray" becomes "this->m_array,5".
Incremental search: While having a source document open hit (CTRL + I) and type the word you are searching for you can hit (CTRL + I) again to see words matching your input.
You can use the following codes in the watch window.
#err - display last error
#err,hr - display last error as an HRESULT
#exception - display current exception
Ctrl-K, Ctrl-C to comment a block of text with // at the start
Ctrl-K, Ctrl-U to uncomment a block of text with // at the start
Can't live without it! :)
Stopping the debugger from stepping into trivial functions.
When you’re stepping through code in the debugger, you can spend a lot of time stepping in and out of functions you’re not particularly interested in, with names such as GetID(), or std::vector<>(), to pick a C++ example. You can use the registry to make the debugger ignore these.
For Visual Studio 2005, you have to go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio \8.0\NativeDE\StepOver and add string values containing regular expressions for each function or set of functions you wish to exclude; e.g.
std::vector.*::.*
TextBox::GetID
You can also override these for individual exceptions. For instance, suppose you did want to step into the vector class’s destructor:
std::vector.*::\~.*=StepInto
You can find details for other versions of Visual Studio at http://blogs.msdn.com/andypennell/archive/2004/02/06/69004.aspx
Ctrl-F10: run to cursor during debugging. Took me ages to find this, and I use it all the time;
Ctrl-E, Ctrl-D: apply standard formatting (which you can define).
TAB key feature.
If you know snippet key name, write and click double Tab. for example:
Write
foreach
and then click tab key twice to
foreach (object var in collection_to_loop)
{
}
2. If you write any event, write here
Button btn = new Button();
btn.Click +=
and then click tab key twice to
private void Form1_Load(object sender, EventArgs e)
{
Button btn = new Button();
btn.Click += new EventHandler(btn_Click);
}
void btn_Click(object sender, EventArgs e)
{
throw new Exception("The method or operation is not implemented.");
}
btn_Click function write automatically
in XAML Editor, Write any event. for example:
MouseLeftButtonDown then click tab
MouseLeftButtonDown="" then click tab again
MouseLeftButtonDown="Button_MouseLeftButtonDown" in the code section Button_MouseLeftButtonDown method created.

More Visual Studio tips and tricks than you can shake a stick at.
Some others:
The Visual Studio 2005 and 2008 3-month trial editions are fully-functional, and can be used indefinitely (forever) by setting the system clock back prior to opening VS. Then, when VS is opened, set the system clock forward again so your datetimes aren't screwed up.
But that's really piracy and I can't recommend it, especially when anybody with a .edu address can get a fully-functional Pro version of VS2008 through Microsoft Dreamspark.
You can use Visual Studio to open 3rd-party executables, and browse embedded resources (dialogs, string tables, images, etc) stored within.
Debugging visualizers are not exactly a "hidden" feature but they are somewhat neglected, and super-useful, since in addition to using the provided visualizers you can roll your own for specific data sets.
Debugger's "Set Instruction Pointer" or "Set Next Statement" command.
Conditional breakpoints (as KiwiBastard noted).
You can use Quickwatch etc. to evaluate not only the value of a variable, but runtime expressions around that variable.
T4 (Text Template Transformation Toolkit). T4 is a code generator built right into Visual Studio
Custom IntelliSense dropdown height, for example displaying 50 items instead of the default which is IMO ridiculously small (8).
(To do that, just resize the dropdown next time you see it, and Visual Studio will remember the size you selected next time it opens a dropdown.)
Discovered today:
Ctrl + .
Brings up the context menu for refactoring (then one that's accessible via the underlined last letter of a class/method/property you've just renamed - mouse over for menu or "Ctrl" + ".")
A lot of people don't know or use the debugger to it's fullest - I.E. just use it to stop code, but right click on the red circle and there are a lot more options such as break on condition, run code on break.
Also you can change variable values at runtime using the debugger which is a great feature - saves rerunning code to fix a silly logic error etc.
Line transpose, Shift-Alt-T
Swaps two line (current and next) and moves cursor to the next line. I'm lovin it. I've even written a macro which changed again position by one line, executed line transpose and changed line position again so it all looking like I swapping current line with previous (Reverse line transpose).
Word transpose, Shift-Ctrl-T
When developing C++, Ctrl-F7 compiles the current file only.
Document Outline in the FormsDesigner (CTRL + ALT + T)
Fast control renaming, ordering and more!
To auto-sync current file with Solution Explorer. So don't have to look where the file lives in the project structure
Tools -> Options -> Projects and Solutions -> "Track Active Item in Solution Explorer"
Edit: If this gets too annoying for you then you can use Dan Vanderboom's macro to invoke this feature on demand through a keystroke.
(Note: Taken from the comment below by Jerry).
I'm not sure if it's "hidden", but not many people know about it -- pseudoregisters. Comes very handy when debugging, I've #ERR, hr in my watch window all the time.
Ctrl-Minus, Ctrl-Plus, navigates back and forward where you've been recently (only open files, though).
I don't use it often, but I do love:
ctrl-alt + mouse select
To select in a rectangular block, to 'block' boundaries.
As noted in comments,
alt + mouse select
Does just a plain rectangular block.
Here's something I learned (for C#):
You can move the cursor to the opening curly brace from the closing curly brace by pressing Control + ].
I learned this on an SO topic that's a dupe of this one:
“Hidden Secrets” of the Visual Studio .NET debugger?
CTRL + Shift + U -> Uppercase highlighted section.
CTRL + U -> Lowercase the highlighted section
Great for getting my SQL Statements looking just right when putting them into string queries.
Also useful for code you've found online where EVERYTHING IS IN CAPS.
Middle Mouse Button Click on the editor tab closes the tab.
To display any chunk of data as an n-byte "array", use the following syntax in Visual Studio's QuickWatch window:
variable, n
For example, to view a variable named foo as a 256-byte array, enter the following expression in the QuickWatch window:
foo, 256
This is particularly useful when viewing strings that aren't null-terminated or data that's only accessible via a pointer. You can use Visual Studio's Memory window to achieve a similar result, but using the QuickWatch window is often more convenient for a quick check.
