I'm trying to trigger a keyboard shortcut to the linux Anki app, but xdotool search --class "Anki" returns 17 window IDs. Sending the shortcut to one of these does work, but using the others gives a list of errors. Is there a way to just get the "correct" window? (and why are there many anyway?)
(A partial solution was to search with onlyvisible: xdotool search --onlyvisible --class "Anki", but this requires the window not to be minimized.)
