Command is not the right word. It’s actually markup, more specifically, HTML. That’s the tag for the <kbd> element. And using it is easy. See <kbd>this</kbd> will produce this
For example, if you wish to do Control + O: <kbd>Ctrl</kbd>+<kbd>O</kbd> produces Ctrl + O
I tried it using above scripts but the panel didn’t work properly on kde. After some searching, I found that there is a plugin to set video wallpapers from settings itself.
The wid option must be an integer: WID
Error parsing option wid (option parameter could not be parsed)
Setting commandline option --wid=WID failed.
Exiting... (Fatal error)
mpv died, exit status 1
If you get this error above while running the xwinwrap command on the Setup part of the tutorial change the WID of the command to %WID.
(Try to run the original command on your terminal to reproduce the error, if it happens it won’t work on startup if you don’t change the WID to %WID)
