Multi-cursor

Instead of having just one cursor, you can create a multi-cursor to allow you to make edits (such as indenting) to multiple lines of code at the same time.

Action	Windows / Chromebook	Mac OS
Add multi-cursor above	Ctrl-Alt-Up	Ctrl-Option-Up
Add multi-cursor below	Ctrl-Alt-Down	Ctrl-Option-Down

Selecting Text

These shortcuts can help you easily select text in your code to copy or cut:

Action	Windows / Chromebook	Mac OS
Select All	Ctrl-A	Command-A
Select Line Up / Down	Shift-(Up/Down)	Shift-(Up/Down)
Select Word Left / Right	Ctrl-Shift-(Left/Right)	Option-Shift-(Left/Right)

Find / Replace

This can be useful if you want to change the name of a variable or element and want to edit all instances of that variable in your program at the same time.

Action	Windows / Chromebook	Mac OS
Find	Ctrl-F	Command-F
Replace	Ctrl-H	Command-Option-F
Find Next	Ctrl-K	Command-G
Find Previous	Ctrl-Shift-K	Command-Shift-G
