Binding a command to Super+F4 does not work

Desktop Environments XFCE

I’m trying to bind (Settings Manager → Keyboard → Application Shortcuts) xkill to Super+F4, where Super is obviously the “Windows” key. (specifically Left Super)

However, Super+F4 does not work. Super+F3 and Super+F5 do, but not Super+F4.

And before you ask, nano ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml won’t help. I tried it to no avail (manually editing the config).

I also noticed that “Generic 105-key PC” was selected, even though my keyboard (Logitech K350) definitely does not have 2 Super keys (Right Super is replaced with an Fn key, and those are never visible to the OS), and is definitely not an international keyboard. Picking “Generic 104-key PC” doesn’t help, neither does 101-key (102-key is international to my knowledge). Whether this is actually a problem, I do not know.

How do I fix this issue?

i looked around a bit and found this : “Logitech’s advanced keyboards, like the K350, require special drivers to map all keys correctly.”
so idk , maybe look at driver support ?
( you’re sure the super+F4 isn’t used by some other system setup ?)

maybe you need to run xkill through a terminal something like
alacritty -c xkill

replace the appropriate terminal and command switch

That’s what I thought, but I set up the Super-F4 binding on my Debian Xfce install. It was working.

@yum13241 - is the ALT+F4 binding closing windows so you know the F4 key itself is working?

Yes, the F4 key is working, it is not broken. Assigning something like Ctrl+Shift+F4 also works.

by default the xkill use the keys ctrl+alt+esc
on my xfce it works at least

Yes, but I’m used to Super+F4, since on Windows I used to use an app called SuperF4 that was basically SIGKILL for Windows, and it had a Super+F4 binding for the xkill simulation.
