Title: Remapping Super_L and Super_R (win keys) like FN
Post by: Barbastruzzolo on Tue, 07 January 2014, 04:19:17

I want to remap my left and right Super keys to behave similarly to the FN key on my Ducky Mini ISO.

At work I use a DK9087S (ISO UK) on Debian Linux (XFCE). I never really understood xmodmap usage...

I would like to create shortcuts like this:

Super_R + W = Up
Super_R + A = Left
Super_R + S = Down
Super_R + D = Right

Super_L + .  = End
Super_L + ; =  Home

How can I do that?
Do I need to install additional software or what?

I already remapped my CAPS LOCK as backspace using xmodmap...


Thank you

You cannot do this with xmodmap, but you can use xkbcomp, which you should
already have.

1. Dump you current layout:

   xkbcomp :0 mylayout.xkb

2. Edit mylayout.xkb.  In section xkb_types, add a type definition like this.

   type "SHIFT+SUPER" {
        modifiers= Shift+Super;
        map[Shift]= Level2;
        map[Super]= Level3;
        map[Shift+Super]= Level3;
   preserve[Shift+Super]= Shift;
        level_name[Level1]= "Base";
        level_name[Level2]= "Shift";
        level_name[Level3]= "Super";
   };

   and in section xkb_symbols, change the definition of key <AD02> to:

   key <AD02> {
        type= "SHIFT+SUPER",
        symbols[Group1]= [   w,             W,             NoSymbol  ],
       actions[Group1]= [   NoAction(), NoAction(),  RedirectKey(key=<UP>, clearMods=Super) ]
   };

   and similarly with the other keys you want to remap.

3. Upload your modified layout to the Xserver:

   xkbcomp mylayout.xkb :0

You can keep mylayout.xkb, and maybe put the last command above in whatever
startup file Xfce might use.

Thank you very much Pro XKB!
 It works!

I'm going to look forward for other layout customizations  :)
