问题:

IDEs based on the IntelliJ platform let you split the editor in various ways, but I don't see an option to move focus from one editor to another using just keyboard (something like other-window from Emacs).

Is there an "action" to do that?

回答1:

For mac users, the default shortcut is alt+tab

回答2:

I think you're already find answer, but for someone who have same question and find this post like me. Go to Prefernces -> Keymap or simple use search in preference and find Goto Next Splitter and make your own hotkey for this action.

回答3:

Main Menu Window | Editor Tabs | Select Next/Previous Tab

There's also Switcher (Ctrl+Tab) available in the same menu as Goto Next/Previous Splitter which switches between splitted editor parts, tool windows, and many other things.
