Keyboard shortcut to switch between horizontally split windows in Intellij

Question

I've done numerous searches to find out how to switch between two files that are horizontally split but can't seem to find it.

Thanks!

Answer 1

I just tried this out, and Goto Next Splitter (Option-Tab on mac) works just fine for me on horizontally split panes

Note: Using CLion 2017.1.2

If you have IdeaVim installed, you can use the Control-W - J/K command to switch between Vim split panes. See also How do I switch between panes in split mode in Vim?
