My laptop keyboard is little annoying – it have a Print Screen(PrtSc) button between my right control and alt keys – usually around that area you will find the windows(super) key, so I wanted to remap it, when i am using i3wm.
So first of all you need to make sure what is your key “called”, you can to that with the
Then you need to get your modifier map with:
In my case my output was this:
xmodmap: up to 4 keys per modifier, (keycodes in parentheses): shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x42) control Control_L (0x25), Control_R (0x69) mod1 Alt_L (0x40), Alt_R (0x6c), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb)
I use mod4 for my i3 config, so I needed to add the Print key to the mod4 modifier with this command:
xmodmap -e "add mod4 = Print"
After that we see that Print is added to the mod4:
mod4 Print (0x6b), Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf), Print (0xda)
And you will probably want to add this command to your i3 config so it get excuted on each boot:
exec --no-startup-id /usr/bin/xmodmap -e "add mod4 = Print"
