autohotkey scancode in combination

Question

I am having trouble getting either of the following to work:

VKFF & a::^a
SC163 & a::^a

This fails with "invalid hotkey" if I try to run the script. The scan code alone works just fine

SC163::^a

I am guessing there is a syntax issue... Any help would be much appreciated!

EDIT:

#InstallKeybdHook
SC163 & a::
    Send, ^a
    KeyHistory
return

Answer 1

You have to use VK and SC together.

Add it to a directive to check if it's pushed or not, then add your a:: hotkey to that directive.

It should look something like this:

#If GetKeyState("VKFFSC163", "P")
a::^a
#If
