A keyboard shortcut to comment/uncomment the select text in Android Studio

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.

To comment/uncomment one line, use: Ctrl + /.

To comment/uncomment a block, use: Ctrl + Shift + /.

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 + -

From menu, Code -> Comment with Line Commment. So simple.

Or, alternatively, add a shortcut as the following:

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 [![First step, find the IDE shortcuts : cmd + shift + A enter shortcuts] 2]2

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

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

On Mac you need cmd + / to comment and uncomment.

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)

/**
 * $comment$
 */

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).

Windows 10 and Android Studio: Ctrl + / (on small num pad), don't use Ctrl + Shift-7!

Default shortcuts is under Preferences -> Keymap -> Main Menu -> Code menu

• Add a shortcut for a single line comment (e.g. Ctrl+ ...)
• Add a shortcut for a block comment (e.g. Ctrl+...)

You can use default one or customize it by right click
