You can also put this at the very top of the file (in the "auto-execute" section). It does exactly what it says.
SetNumLockState, AlwaysOn

Personally, I like to use Num Lock to show/hide an instance of the Calculator app.
WinToggle(Title,EXE) {
DetectHiddenWindows, on
If WinExist(Title) {
If WinActive(Title) {
WinMinimize
WinHide
} else {
WinShow
WinActivate
}
} else {
Run %EXE%
}
}
NumLock::WinToggle("Calculator","Calc")
