i cant see exactly where in your code you would want this but basically just do
tHistory[h] = string.sub(tHistory[h], 1, -2)

Nvm..
For future solutions: string.sub works

tHistory[h] = string.sub(tHistory[h], 1, string.len(tHistory[h]) - 1 )

why all of the code? you should just pick it up as normal and then say
that way it adds caps and lowercase fine and just leaves out the keys that aren't chars
if key~="backspace" and key~="enter" then -- and keep doing that to leave out irregular keys tHistory[h]=""..tHistory[h]..key end
that way it adds caps and lowercase fine and just leaves out the keys that aren't chars

I tried that earlier (above) it works, but this looks so much cooler. Having thousands of lines of if statements.. lmao.
IDK, It'll show my hard work (IN NPP).
EDIT: It's weird, I have to block key lshift and rshift.
EDIT: Caps don't work.

yeah, you have to block any key that cc recognises as an event that does not enter in a character, there is of course a very simple way to do it, just return the length of 'key' and only add it to tHistory if it is 1 character long...

because anything that is not a typable character has a key description and that is always at least 3 chars long

then you add arrow key, enter and backspace/delete functionality and you have a functioning input receiver
the problem is while you have no doubt put a lot of work into writing all of those if statements the PC now has to put that much effort into reading it every time you press a key, this drastically slows things down
