Remap a single key (or keymapping in general)

English Applications
#1

Hi,

I want to remap a single key on my keyboard. This is the key which will delete or in numpad mode will put a ‘.’ or a ‘,’ in my case.

I want the ‘,’ to be a ‘.’ .

So I found out that xev gives me some information about the keys.

So I tried something like

xmodmap -e ‘keycode 91 = period’

Which is not what I want. Because than the delete command gets overwritten instead of the comma. So I tried

xmodmap -e ‘keysym 0x0 = period’

Which looked like a endless loop to me. 0x0 is also quite strange, isn’t it? But this is what xev gave me for numlock activated and the comma-key.

The difference between the delete and the comma is the “state”.

Xev returns for delete:

KeyRelease event, serial 34, synthetic NO, window 0x4800001,
    root 0x10c, subw 0x0, time 1934052, (412,580), root:(416,605),
    state 0x0, keycode 91 (keysym 0xffff, Delete), same_screen YES,
    XLookupString gives 1 bytes: (7f) ""
    XFilterEvent returns: False

The comma key gives:

KeyRelease event, serial 34, synthetic NO, window 0x4800001,
    root 0x10c, subw 0x0, time 1323230, (350,498), root:(354,523),
    state 0x10, keycode 91 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

The difference is the state. So the questions: How do I get the comma to behave like period/dot?

Okay

xmodmap -pke

lead me to

xmodmap -e 'keycode 91 = KP_Delete period KP_Delete period KP_Delete period'

Which does the trick. Thank you for reading.
