How to undo accidental inconification / minimization
Emacs has the property that it iconifies/minimizes itself when the user presses Ctrl-Z - and this seems to work even if the window manager does not support iconification.
So if I accidentally press Ctrl-Z in Emacs, the window seems to be gone completely (but I can tell that the process is still there).
Is there any way to get the window back using i3?
(On the emacs side, it might be possible to do undo this by sending some lisp commands via emacsclient, but that only works if emacsserver has been started before the accident).
What i3 version are you using? Iconification was touched and reverted in i3 recently.
