Unsupported input method for `#` symbol

[Tenchi2xh]

With my current keyboard layout (Swiss French), to input a # symbol for extend commands, the combination is AltGr + 3, which does not work with the current build

Also on a side note, support of the subkeyvalue option would be greatly appreciated, for the following swap of the Z and Y keys (my QWERTZ keyboard makes it hard to use HJKL YU NM for movement):

OPTIONS=subkeyvalue:121/122
OPTIONS=subkeyvalue:122/121
