.xmodmaprc
This modification works best in conjunction with the USA International (AltGr dead keys) layout. Switch [Esc] and [CapsLock], put 'ł' and 'Ł' on 'w' and 'W', diaeresae on 'a', 'o' and 'u', make keypad dot an actual dot, put '/' and '\' on Super_R (a legacy from using the CyMotion Pro which had a dedicated @-sign there).

Super_L
The Super_L key doesn't seem to work as expected on Fedora. Usually, the Super_L settings can be omitted.
