Sure, no problem at all. I use a tiling window manager. For this I have a script for navigating between OS windows and for consistency I use the same script to navigate windows in Emacs. The script uses emacsclient --eval “(evil-window-up 1)” to navigate a window up, if this fails it will call the window manager instead because it means that there is no window in that direction. Because the wait is now 2 seconds it takes 2 seconds to shift focus out of emacs. This might be a minor nuisance but enough to be annoying.
