Global keyboard function in Autohotkey?

问题

This script "auto-presses" E while holding it down.

    $e::
While GetKeyState("e","P")
{
    Random, r, 50, 250
    sleep r
    Send e
}
return

Is there a way to globally call this function for any key?

For example: Holding A, will auto-press A and Z will auto-press Z, etc.

Without manually assigning every possible key on the code.

I am not aware of a way to catch all keys. But you can simplify your code by combining hotkeys this way:

$a::
$b::
$c::
; and so on...
$z::
RandomSendCurrentKey()  ; all the above hotkeys will call RandomSendCurrentKey()
return  ; 'return' is needed to prevent further execution

RandomSendCurrentKey() {
    local key
    StringReplace, key, A_ThisHotkey, $,, All  ; removes '$' from key   

    While GetKeyState(key, "P")
    {
        Random, r, 50, 250
        sleep r
        Send %key%
    }   
}

But why do you need a while loop? It should work without a while too since AutoHotKey will keep calling the function as long as you press the key:

$a::
$b::
$c::
$z::
RandomSendCurrentKey()
return

RandomSendCurrentKey() {
    local key
    StringReplace, key, A_ThisHotkey, $,, All  ; removes '$' from key   

    Random, r, 50, 250
    sleep r
    Send %key%
}
