I have read that xmodmap has been overridden by xkb since Fedora 23. I am using i3.xkb seems really overwhelming when all I want to do is swap the windows key and alt key.From xev the outputs are:Windows Keykeycode 133 (keysym 0xffeb, Super_L)Alt Keykeycode 64 (keysym 0xffe9, Alt_L)
Remap Fedora 23 Keys under the i3 window manager
fedora;keyboard shortcuts;keyboard layout
I figured out how to do achieve this finally using setxkbmap.setxkbmap -model thinkpad60 -layout us -variant int -option altwin:swap_alt_winYou can find the premapped options in /usr/share/X11/xkb/rules/evdev.lstYou will need to add this to your startup file because the command only last as long as the session you execute it in.
