I would like to implement some Greek characters into my keymap in the console (tty). I am using Arch Linux and the directory I am working in is /usr/share/kbd/i386/qwerty/uk.map, although I don't know if this is the right place to deal with the problem.
The expected result should be:
Key pressed: d
Shift (or Caps Lock) pressed + letter: D
Alt Gr + letter: δ
Shift (or Caps Lock) pressed + Alt Gr + letter: ∆
...just like this, but in the console.
