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

Question

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 cor

Answer 1

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

Answer 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
