I set up my keyboard layout in
/usr/share/X11/xkb/symbols/ to use the keys H J K L as arrows Left, Down, Up and Right as the third and fourth shift level. mostly I followed this post.
The Right Alt is my Alternative Characters Key.
While this customization will "basically" work, I can not select text by typing it in conjunction with
SHIFT . For example, I can not select the text by pressing Alt Gr+Shift+H, as it would do with Shift+Left. But I can jump a whole word with Ctrl.
the HJKL are working exactly like the arrows in Firefox (with shift and Ctrl) but not on Gedit, Rhythmbox or Chrome, and possibly more...
Any ideas? I'm using Ubuntu 14.04.
Edit:I am using a german keyboard with AltGr. and the files are the fowllowing:
