KDE: find who is capturing keys combination

usr345 · 09-04-2020, 04:20 PM

I'm using Slackware 14.2, Emacs version: GNU Emacs 26.3 (build 1, i586-slackware-linux-gnu, GTK+ Version 3.18.9) of 2019-08-29.

I want to attach an action to "Super-s" key combination in Emacs:

Code:

(define-key global-map [?\s-s] (lambda () (interactive) (message "hello-world")))

A person, who suggested me this says, that it works for him on Emacs 25, Emacs 26, Emacs 27 on Apple/Mac computer. He ran Emacs -Q to disable any configs interference.

I tried the same, it didn't work. "Ctrl-h k s-s" shows nothing. The key combination must be captured by KDE window manager.

How to find who is capturing it and disable?

Have you checked KDE System Settings-->Customize Appearance and Behavior-->Shortcuts and Gestures-->Keyboard Shortcuts to see whether there might already by a conflicting shortcut?

I did. There is nothing there with Super key. Can you reproduce my problem on your system if you also use Slackware?

Run $ emacs -Q, then click:

"Ctrl-h k", then "Super-d". It says "s-d undefined".
"Ctrl-h k" - "Super-s". Nothing happens.
