Keybinds using IF

Hello

If I pressed 1 at any time since the script has been running
x::e
z::q

If I pressed 2
a::e
s::q

I cant figure out how to do it. Hopefully someone can help me.
Thanks!

eDIT: Named the thread using IF but I think it has to do with vars. New at this but thats the most Im getting from reading. ^^
