http://forums.fedoraforum.org – Hi all. Going a little nuts over a small issue ... For the life of me I can't seem to enable the keyboard options button in > System Settings > Region & Language > Input Sources. (the little button with the spanner and screwdriver?? Background to the problem is: I don't type in QWERTY. I type in Colemak. So I've added the extra input source to specify the Colemak keyboard layout. The actual problem is I can't enable the options button to specify some of those ESSENTIAL keys like Alt being mapped to Alt. I type a lot, and use right Alt, as Alt, about 80, 10 (HowTos)
