//
// This layout is based on the following needs:
//
// should be as close as possible to querty/us-international layout (using international/AltGr as o/s driver)
// added german umlauts at known places from de-layout
// all movement keys should be at known places from vi/bash (eg HJKL for cursor keys)
// Fn layer (at CapsLock place like the Pok3r does) for missing keys
// additional layer for tmux window switching
//
// This is work in Progress! If you have suggestions write me at github.com/mollat/qmk_firmware/ and check
// this fork for updates as I probably won't bother jack with my pull requests frequently.
