If(Key.isDown(Key.getAscii() == 65)) not working (checking for letter "A") if pressed

1

I am trying to figure out how to check when the key “A - Z” is pressed…

How can I use ASCII characters to check this?, or even if I check something like this

if(Key.isDown(Key(“A”)))

I’d appreciate if someone could tell me how to check when keys A-Z are pressed…

preferably something like this

onKeyPress(“A”) = function()
{
“run code”
}

anyway to do this?

basically hotkeys, press “s” to call a line of function that will save the game… etc…
