Remap any key to win

Question

I've tried a lot of combinations to map my key AE12 to Super (win key) but all them failed...

How can i map a key to act like win key in /usr/share/X11/xkb/symbols/us ?

I am using linux mint.

Noticed that after reboot layout reverts to previous version plus it displays wrong layout on keyboard graphical layout representation. If after reboot i remove my layout and add it back thought menu then it applies and keys are remapped correctly. But in graphical representation it remains old. After new reboot - same story.

Maybe i need to clean some cache?

Answer 1

Try adding this to your ~/.Xmodmap

keycode 21 = Super_L
add mod4 = Super_L

Then make sure your desktop manager parses it at start. If it doesn't, add to you ~/.xinitrc

xmodmap ~/.Xmodmap

In your key AE12's keycode isn't 21, use xev to find out the right code. In my case, that key is the key immediately to the left of the backspace key.

I didn't use my machine for a while. And when it was booted, my mappings were working like a charm. So it seems was a cache issue...
