title: IntelliJ Split Window Navigation
body: <p>If I split the editor window (horizontal or vertical) into N tab groups, how do I switch/toggle from one tab group to another via the keyboard?  If all of the tabs are in the same group you can switch from each tab easily (CTRL + right/left arrow), but when they're in separate tab groups I can't.  I've searched through the key mappings and have not found one that seems to accomplish this.  I know I can use the mouse, but I'm trying to find ways to avoid the mouse and stay with the keyboard. </p>
  
  <p>TIA for any help on this.</p>
