I think the steps to recreate might be the easiest way to describe my issue:

• Go to System Settings -> Custom Shortcuts -> Edit -> New -> Global Shortcut -> Send Keyboard Input
• Set the trigger to be Ctrl+Alt+Shift+T
• Set the action to be "t:e:s:t" without the quotes
• Apply the changes
• Test shortcut somewhere like a text editor

The expected result would be to see the text "test" appear but instead I get "est". Changing the action to "t:t:e:s:t" gives me "test". If I just change the shortcut to Ctrl+Alt+Shift+S then the input text is "tet". It seems like it is dropping the first occurrence of the key used in the trigger.

I previously had a few shortcuts set up that worked fine. It was sometime in the past few weeks that the behavior changed to the current. Any ideas what is causing this? Or ideas for a fix better than doubling the first instance of the trigger key?

System information:

• Kernel Version: 5.9.16-1-MANJARO
• KDE Plasma Version: 5.21.2
• KDE Frameworks Version: 5.79.0
• QT Version:5.15.2
• OS Type: 64-bit
• Graphics Platform: X11

Same Plasma version here, and the Shortcut produces nothing at all. So either I am doing something wrong, or something is definitely broken, but that should be reported to https://bugs.kde.org. The forum is the wrong place for bug reports.

Thanks for checking on your end. I wasn't sure if I was just being dumb or if this was an actual issue. I followed up with a bug report Bug #434251.
