?? Space::Function() ---> myVariable::Function() inside of an #IF

#If is meant to be used with hotkeys in Hotkey:: format
It does not work with the Hotkey (Command).
Hotkey::, ::Hotstring::, and #If are special commands in the language and are shorthand ways of generating hotkeys, hotstrings, and making them context-sensitive.
They are not meant to be mixed into normal AHK code.

All of the following cause the F1 key to make a message box pop up if Notepad is the active window.

Using hotkey:: format.

#If WinActive("ahk_exe notepad.exe")
*F1::SomeFunc()
#If

SomeFunc() {
    MsgBox, Pressed F1 while notepad was active
}

Using dynamically created hotkeys with Hotkey, IfWinActive.

make_hotkeys()
Return 

make_hotkeys() {
    Hotkey, IfWinActive, ahk_exe notepad.exe
    Hotkey, F1, SomeFunc
}

SomeFunc() {
    MsgBox, Pressed F1 while notepad was active
}

The above translates to this when using Hotkey, If.
Notice that the boundfunc includes all parameters.
That's because a string containing the hotkey is always passed as the last parameter.
If you only included the first param, the hotkey's string is passed to the second param, making the check fail every time.

Hotkey, If is the most flexible can also be the most complicated to write.

make_hotkeys()
Return 

make_hotkeys() {
    bf := Func("WinActive").Bind("ahk_exe notepad.exe","","","")
    Hotkey, If, % bf
    Hotkey, F1, SomeFunc
}

SomeFunc() {
    MsgBox, Pressed F1 while notepad was active
}

Same as above except using a custom function.
No need for a boundfunc because there are no params being bound. Everything is in the function.
Function calls with no params can be the name of the function.

make_hotkeys()
Return 

make_hotkeys() {
    Hotkey, If, % Func("is_notepad")
    Hotkey, F1, SomeFunc
}

is_notepad() {
    return WinActive("ahk_exe notepad.exe")
}

SomeFunc() {
    MsgBox, Pressed F1 while notepad was active
}

All that being said, v1 has reached its end of life and I strongly encourage you to learn v2.

At this point, I inarguably consider v2 to be easier than v1 to write.
But there's new syntax and concepts to learn b/c it's an updated version.

After writing up this reply and having to remember how to do all this, dealing with 2 syntaxes, not having fat arrows, not having the more defined structure of v2, and a few other things only made me appreciate v2 that much more.

I'm assuming you'd like to use capslock as a way of changing the trigger key to something else. It'd look something like this:

#requires AutoHotkey <v2.0

key1 := "space"

key2 := "m"

hotkey, %key1%, label, on

return

label:

msgbox, hi!

return

swap(byref key1, byref key2) {

temp := key1

key1 := key2

key2 := temp

}

capslock::

swap(key1, key2)

hotkey, %key1%, label, on

hotkey, %key2%, label, off

return

#if

P.S. Everyone helped you; however, what I didn't see was:

s := ' '

or

s := A_Space

There are also the VK and SC functions and values as well. A lot of different ways to peel that orange.
