            Bug ID: 482480
           Summary: Key Codes F13 - F24 don't get handled as expected in
                    KDE Plasma
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED

Example: F23 gets recognized as "Touchpad Off"

SUMMARY
***
I have a macropad (running QMK Firmware) which is able to produce key codes
such as F13 - F24.
When trying to assign shortcuts in the System Settings e.g.: F23 will get
recognized as "Touchpad Off" or F13 as "Launch (9)".
I'd expect the system to show F23 as the shortcut button when I assign F23 as
the shortcut - and not  "Touchpad Off".
The System settings shortcuts do work but the F13 - F24 keys don't get
recognized in all applications - not even "wrongly" as e.g.: "Touchpad Off". 
***


STEPS TO REPRODUCE
1. Have a keyboard/macropad where you know for sure that it's able to produce
the key codes for F13-F24.
2. Try to assign a key - that sends F13, F14 etc. -  to a shortcut in the
System Settings.

OBSERVED RESULT
The populated key under Custom shortcuts will not show F13 - F24 but things
like "Launch (9)", "Launch (A)", "Touchpad Off" etc.

EXPECTED RESULT
The populated key under Custom shortcuts shows e.g.: F13 since I pressed F13 on
my macropad. 

___
In the shortcut System settings this is only a "visual bug" (I can use the
shortcut) but e.g.: I can't use F22 at all in my music-player DeaDBeef - only
after creating the .Xmodmap described in ADDITIONAL INFORMATION.
Plasma's correct handling of F13 - F24 is thus also needed for user
applications. 


SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.27.10
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.12

ADDITIONAL INFORMATION

On X11 I was able to "fix" this by using a .Xmodmap file containing:
keycode 191 = F13 F13 F13
keycode 192 = F14 F14 F14
[...]
keycode 202 = F24 F24 F24

This made F13-F24 be recognized as such by the system. 
But this does not work under KDE Wayland.
