How do I comment out several lines of text selected in the IDE with a control key combination?
I thought that Ctrl + Alt + C was the correct sequence, but that's not working.

The answer is
You can also use regions. See https://www.myandroidsolutions.com/2014/06/21/android-studio-intellij-idea-code-regions/
Select a block of code, then press Code > Surround With... (Ctrl + Alt + T) and select "region...endregion Comments" (2).
At least in Android Studio 2.2.3 with default key mapping, to comment or uncomment a select text, same hotkeys are used as Toggle. Using the hotkeys changes the state from comment to uncomment, and next time Uncomment to comment on next and vice versa.
1. Comment / uncomment a block of code
Comment sample: /* --- Code block ---- */
Hotkey: Ctrl + Shift + "/"
Using the same key combinations again will "toggle" commenting or uncommenting the selection.
2. Comment / uncomment a line of code
Comment sample: // -- Code ---
Hotkey: Ctrl + "/"
Using the same key combinations again will "toggle" commenting or uncommenting the selection.
Note: Key mapping can be changed to different schemes like eclipse, visual studio... or to the custom hotkeys in File -> Settings -> Keymap
if you are findind keyboard shortcuts for Fix doc comment like this:
/**
* ...
*/
you can do it by useing Live Template(setting - editor - Live Templates - add)
/**
* $comment$
*/
I had the same problem, usually, you have found the shortcut but it doesn't work because you have not a NumPad. Actually, the only one issue I found is to set my own shortcut with the one I suppose should works.
First step, find the IDE shortcuts : cmd + shift + A enter shortcuts
Second step : Find Comments Shortcut with the finder
Third step : Set your custom shortcut (I suggest cmd + shift + / or cmd + : )
Now enjoy, it works on a macBook without NumPad
edit : cmd + shift + : has conflicts
Edit : this both works without conflicts
Issue on MacBook
On Mac you need cmd + / to comment and uncomment.
MAC QWERTY (US- keyboard layout) without numpad:
Line comment : ? + /
Block comment: ? + ? + /
MAC QWERTZ (e.g. German keyboard layout):
Android Studio Version ≥ 3.2:
Line comment : ? + Numpad /
Block comment: ? + ? + Numpad /
thx @Manuel
Android Studio Version ≤ 3.0:
Line comment : ? + -
Block comment: ? + Shift + -
Windows 10 and Android Studio: Ctrl + / (on small num pad), don't use Ctrl + Shift-7!
From menu, Code -> Comment with Line Commment. So simple.
Or, alternatively, add a shortcut as the following:
