I'm on an Italian keyboard. Accessing ` and ~ is so frustrating (I have to enter Alt + 9 + 6 and Alt + 1 + 2 + 6), but I also have a useless § key (Shift + ù). I'd like to "add a layer" to the \ key, so pressing AltGr + \ will produce ~ and AltGr + ' will make `.
Another nice thing to add is support for dead keys. I'd like to have a single pressure to behave as usual and (AltGr + Shift) + pressure let it behave as a dead key.
So to add e', I just enter e + '. To enter é, I enter AltGr + Shift + ' and then E.
What is the solution?
*Note: switching to IT-104 is not an option, as it remaps ~ to ], so I'll gain the gliphs, but at the cost of losing another that was well memorized.
