Comment 24 for bug 36812

Daniel, thank you for the answer. Further clarification (just in case):

a) F1 was just an example -- alt+left, alt+enter, alt+<anything not defined as character> is not working.

b) I don't use ctrl+alt, I use only alt (for getting special characters, in fact since alt is a key I cannot use anymore (*) I cannot use alt+ctrl anywhere by definition)

c) alt also is an example, in general it is shift level 3 key, it could be meta key as well

(*) sorry for using term "dead key", it has special meaning in X (other than I meant)

In short my wish is:
alt+c --> ć (character)
alt+f --> alt+f (key combo; so I could use in KDE as a keyboard shortcut)
