With a selected a block of code, I try to indent it by pressing TAB.
I would expect the code to be indented.
Instead, the selected text is deleted and replaced by a TAB.
How come? Is there any other shortcut for this?
As a newcomer to Pharo/Squeak you might expect to indent a block of code by pressing TAB/SHIFT-TAB.
As it turns out, this is not the way it works as of Pharo 1.4 / Squeak 4.3 (however this might change in the future, see comment below).
The correct shortcuts for indenting-Right / indenting-Left are:
Indent (right) Outdent (left)
Win/Linux: Ctl + Alt + R Ctl + Alt + L
Mac: Cmd + Shift + R Cmd + Shift + L
So: it's R/L for right/left.

In Jupyter Notebook, you can toggle/comment a block of selected code with Ctrl + /, but this doesn't work in Google Colaboratory notebooks. Is there a way to comment out several lines of Python code easily in a Colaboratory notebook?
I've looked in the documentation, but I came up short.
In the default Colab keyboard shortcuts, you can block comment text using Ctrl+/.
If this does not work for you, check Tools->Keyboard Shortcuts and search for "Comment Current Line" to see what the shortcut is within your current settings.
You can select the lines of code and press (Ctrl + /) to comment or uncomment your selected lines of code.
You can also use triple single quotes (''') at the start and end of the code block you are interested to comment out.
''' ...Your commented code... '''
If you are a Mac user, you can use Command + / for commenting out, and if you want to uncomment again, select the lines and then Command + /.
For Mac users who don't have an American keyboard like me: it seems like Colab thinks you are using an American keyboard for shortcuts, and so to make the '/' character you have to press the second button to the right of the 'm'. I'll leave an image to explain.
My keyboard looks like this:
As I said, I have to press the . key to make '/' as if I were using an American keyboard.
For Mac users:
first select the lines that you want to comment
second push these buttons: Command + Ctrl + Shift + /
Especially in the Italian keyboard it would be: Command + Ctrl + Shift + 7 (because the "/" character is combined with button "7")
For some reason, I need to do Ctrl + Shift + :.
Which technically is Ctrl + /.
(I use an AZERTYUIOP keyboard.)
if you come here with an Italian keyboard you should press:
command + control + .
When using Mac the keyboard shortcut is ⌘+/.
Note that depending on your layout, / cannot be directly addressed and its combination is different when combined with ⌘. For example, on a German keyboard / is [Shift]+7 but the combination ⌘+/ is ⌘+[Shift]+ß.
When you are unsure about which combination is correct, use the inbuilt keyboard viewer which provides a live view of the meaning of keys while selecting modifiers.
Keyboard Viewer: default keyboard mapping
Keyboard Viewer: modifier keys keyboard mapping
There is a way in webstorm to comment or uncomment a specific line or selected block of source code with shortcut?
I try to use CTRL + / but doesn't work for me

Try to use Ctrl+Slash or Ctrl+Shift+Slash for block comment
If this doesn't work show in your Setting -> Keymap -> Search comment
Use CTRL+/, but with the / located on the numpad.
The question remains why commenting with / (the one besides .) does not work (it does not for me, either).
Ctrl + / ==> To comment/uncomment a line .
Ctrl + Shift + / ==> To comment/uncomment block of code.
Ctrl + Y ==> To delete a line.
On a Mac with an extra keyboard it is CMD + Numpad's /.
The one on the native Macbook keyboard I did not get to work.

On Windows with a German keyboard layoout the default keyboard shortcut for the comment lines action Ctrl+/ conflicts with the bookmark shortcut Ctrl+7. You need to remove the keyboard shortcut for bookmarks in order to get this to work.
#Note Shortcut IntelliJ IDEA
Ctrl + / => comment or uncomment a line -> //
Ctrl + shift + / => comment or uncomment block of code -> /**/
Ctrl + y => delete a line
Ctrl + d => duplicate a line
If Ctrl + Shift + / doesn't work , try Ctrl + Shift + Num Pad /.
You can check the exact configuration in settings->keymap.
Commenting out each line of selected code for Mac users without numpad would have to add a keyboard shortcut:
Navigate to settings: Preferences > Keymap > Main menu > Code
Double click on Comment with Line Comment
Insert your shortcut, for example: cmd + shift + 7 would be interpreted as shift + cmd + 7 but works the same.
I have an AZERTY keypad in French, so this was the answer for me :
Ctrl + Shift + / on the numpad
Because / out of the numpad was detected as :, even with Caps Lock on.
You can check how the keystrokes are actually detected by IntelliJ in :
On Windows :
Settings > Keymap > click on the icon of Magnifying glass with cubes (tooltip is "Find Actions By Shortcut"). In the little tooltip that opens, you stroke the keys and observe the registered results.
On Ubuntu :
Settings > Keymap > click on the icon of Keyboard, right next to the search input (tooltip is "Find Actions By Shortcut"). In the little tooltip that opens, you stroke the keys and observe the registered results.
You need to activate this option:
'Settings' > 'Keymap' > 'Use national layouts for shortcuts (requires restart)'
As said before on Mac Montery 12
on Idea 2020.3
CMD + NumPad /
or from Action dialog:
It is necessary to switch to the English layout
its possible to use inellij IDEA by the way you customized before with an IDE like VisualStudio
Settings -> KeyMap -> Choose your old IDE its a grate! feature life saver :)
try ctrl + shift + 7 or num lock and then ctrl + /
control + / (this is the mathematical one which is located on the numbad)
When I use the Cmd + Shift + / keyboard shortcut to comment/uncomment a block of code, the Help tab on the menu bar in IntelliJ also opens.
Does anyone know how to prevent this shortcut from opening the Help menu tab in IntelliJ 16.1.2? I am using the Mac OS X 10.5+ shortcuts.
Remove or replace the Cmd + Shift + / shortcut in your mac. Apple menu-> System Preferences-> Keyboard -> Shortcuts.
Steps:
Remove or replace the Cmd + Shift + / shortcut on your Mac (as mentioned by #Bajal)
Add new Intellij shortcut Cmd + 7 for "Comment with Line Comment" (Preferences -> Keymap)
I used this work around but it didn't fix the problem:
In IntelliJ, I went to Preferences -> Keymap and I searched for comment. It turns out that there are 3 different commands to comment/uncomment a block of code.
Cmd + Shift + /
Ctrl + Shift + /
Cmd + Alt + /
My work around to prevent Cmd + Shift + / from opening the Help menu tab is to use one of the other keyboard shortcuts.
This doesn't answer my question fully so if anyone has any suggestion please let me know as I would prefer to use Cmd + Shift + /
I had the very same issue. The solution by Bajal helped, because the shortcut didn't trigger the help tab. But it didn't allow me to line comment my code.
So I had to add Shift + Cmd + 7 to the keymap. This is exactly the same as Cmd + /, but I had to add it anyway.
I want to have the 'Ctrl'+'K','Ctrl'+'D' functionality of Sublime in Android Studio, how do I do it?
Perfectly similar to this question, but with respect to Android Studio.
How do I skip a match when using Ctrl+D for multiple selections in Sublime Text 2?
I use Ctrl+D to add to selection (discrete multiple select) the next occurrence of the string (or substring) highlighted. And to skip adding next immediate selection to selection but the one after it, I use Ctrl+K, Ctrl+D. How do I do the same in Android Studio.
I just know Alt+J is similar to Ctrl+D (found from Keymappings in Android Studio).
And to deselect the last selected it's Alt+Shift+D.
But how do I skip next occurrence?
My question is in no way related to:
Does IntelliJ IDEA have a `Ctrl` + `K`, `Ctrl` + `D` equivalent?. That's Visual Studio equivalent. I want the SublimeText equivalent.
Check http://blog.jetbrains.com/idea/2014/03/intellij-idea-13-1-rc-introduces-sublime-text-style-multiple-selections/
Select next occurrence: Alt + J (Ctrl + G for Mac OS X)
Unselect next occurrence: Shift + Alt + J (Shift + Ctrl + G for Mac OS X)
Select all occurrences: Shift + Ctrl + Alt + J (Ctrl + Cmd + G for Mac OS X)
Remove all selections: Esc
Add/remove a selection: Alt + Shift + Mouse Click
It is described in this Issue that was initially created because this skip-next was missing.
Anyhow you just press F3 to skip next possible selection.
If you are using OSX, there are two answers, depending on what keymap you have selected in Preferences:
Keymap : Mac OS X 10.5+
To start / add to your discrete multiple selection : CTRL+G
To skip the current selection and move to the next : CMD+G
Keymap : Mac OS X
To start / add to your discrete multiple selection : CTRL+G
To skip the current selection and move to the next : F3
(this mode is really awkward IMO - no flow)
If you have more follow up questions I had success asking support via this thread : https://youtrack.jetbrains.com/issue/IDEA-121956
Go To Settings -> Keymap -> Main Menu -> Edit -> Find
OR Search for the following options in Settings -> Keymap
Set the shortcuts for the following (Linux/Mac) :
Add Selection for Next Occurrence : Ctrl + D/Cmd + D
Find Next/ Move to Next Occurrence : Ctrl + K/Cmd + K
You might also want to setup Unselect occurrence:
Unselect Occurrence : Ctrl + U/Cmd + U
Carefully remove/replace/override any other existing bindings with these shortcuts according to your needs. You should have Sublime Text Ctrl+D, K behaviour working.
Note: Test these shortcuts for functionality with the default key bindings first. This will ensure, you get working shortcuts with your favourite shortcut keys.
I needed to use sublime's Ctrl+D (switch between multiple selected).
The F3 key worked for me.
I know that Ctrl + N is to find classes and it is very useful. But what about methods?
ctrl + F12 (cmd + F12 on macOS) will show all members of the current class in a popup window and let you pick up one. It works exactly like the ctrl + o shortcut in eclipse, much faster than ctrl + alt + shift + n
Windows : ^ ctrl + F12
MacOS : ⌘ cmd + F12
Above commands will show the functions/methods in the current class.
Press ⇧ SHIFT TWO times if you want to search both class and method in the whole project.
Ctrl + Alt + Shift + N allows you to search for symbols, including methods.
The primary advantage of this more complicated keybinding is that is searches in all files, not just the current file as Ctrl + F12 does.
(And as always, for Mac you substitute Cmd for Ctrl for these keybindings.)
Android Studio on Mac
Command + Option + O
Opens up the Symbol lookup that you can jump to most of the methods/functions in your currently opened document.
Intellij IDEA 2017.3.4 - 2018.2 (Ultimate) on OSX
CMD + fn + F12
will show all members of the current class in a popup window, then you can search method in that class.
BUT, this answer is depends on your Keyboard setting. If your keyboard setting in
System Preferences > Keyboard > Use all F1, F2, etc. keys as standard function keys
is selected, then the shortcut becomes
CMD + F12
CTRL + F12 brings up the File Structure navigation menu, which lets you search for members of the currently open file.
IntelliJ IDEA Version 12.13 Ultimate Edition:
Macs:
command + option + shift + N
or on Menu -> Navigate > Symbol ...
Slightly beside the actual question, but nonetheless useful: The Help menu of Intellij has an option 'Default Keymap reference', which opens a PDF with the complete mapping. (Ctrl+F12 is mentioned there)
If you just want to look for methods:
On mac OS X 10.5+ binding, it is Alt + ⌘ + O
By Default XWin Key binding, it is Shift + Ctrl + Alt + N
You can also press double SHIFT then, you can search anything (not only method, but also class, files, and actions)
It is worth adding that if you want to search for a method of a class, you can use a . (dot) between the class and method name inside of either the search everywhere or search symbols dialog. This even works with IDEAs usual search benefits. For example, you can search for LDT.now and LocalDateTime::now will pop up as a result. (As long as you are searching All Files and not just Project Files).
If you click on a method, you can do Ctrl + B to go to that method's declaration. Similar to F12 in MS Visual Studio.
To Find the actions build in the IDEA(reindent, create new, ...) you can use
CRTL+SHIFT+A
then type indent for example and ENTER.
If I need navigate to method in currently opened class, I use this combination: ALT+7 (CMD+7 on Mac) to open structure view, and press two times (first time open, second time focus on view), type name of methods, select on of needed.
Intellij v 13.1.4, OSX
The Open Symbol keyboard shortcut is
command+shift+s
Ctrl + Shift + Alt+ 7 after selecting the method
I tried SHIFT + SHIFT and ALT + CMD + O
But I think the most powerful and easy to use feature is find in all files CMD + SHIFT + F.
Choose regex and write .*partOfMethodName.*\( and it shows all places and can see the actual source code in place without going to that specific file.
