I type a lot Unix commands and I need often "~" and "`" which in U.S. keyboards are on the key under the escape key.
I'm now using an Apple spanish keyboard set to U.S. layout, and this key is mapped to the characters "§" and "±" instead. I can't find "~" and "`" anywhere, and I need them exactly at their usual place anyway.
Is there an easy way to remap the key that doesn't affect other users? (they use the Spanish layout). I'd rather not use apps like Karabiner that ask to "control my computer" as I don't know what else it does, if possible. Thanks.
