What is the shortcut to split editor window?

Question

Is there a way to split your window vertically with a keyboard shortcut?

Right now I have to Ctrl+Shift+A and choose split vertically.

There is no mention of a shortcut here: Splitting and Unsplitting Editor Window

Answer 1

File->Settings->Appearance & Behavior->Keymap Search for Split Then you may define your own keyboard shortcut.

Answer 2

For IntelliJ 2020.3 (Mac) the command is now called Split-Right. Context-Click on a tab and Split-right will create a new window to the right.
