Is there any way of adding letters/signs to individual keys or function keys ?
Sine I have been looking for the Tilde ~ sign but i went through all 4 of the keylayouts in settings/keyboard and I can not find any key or key combination to write the Tilde sign.
To program an Function key would be OK or replace some other obsolete signs on the keyboard map

and try according to amar's answer?
