Autohotkey is executing everything past my loop's end

Question

I'm using autohotkey to make (hjkl) my arrow keys, and scroll faster without doing pagedowns/ups, which makes reading textbooks with large illustrations easier.

The problem is that ahk is executing everything once my "spacebar" loop is finished. Ex. in the code below, it will go 16 spaces down, and one space up. It shouldn't go one space up unless I press "z".

Suspend On

h::Left
j::Down
k::Up
l::Right

space::
    Loop,8{
        Send {Down}
        Send {Down}
    }

z::
    Send {Up}

+Capslock::
CapsLock::Suspend Off
CapsLock Up::Suspend On

I've watched a few tutorials on loops now and I don't see how I could be doing anything wrong. The rest of the code works.

Answer 1

You need to return at the end of each multi-line method or hotkey. Otherwise, by logic, you haven't specified when a certain method ends. Note that single line methods have an implied return statement.

I've cleaned up and fixed your script (I have strict style on commas, capitalization, indentation/whitespace, and placing brackets on their own line):

Suspend, On

h::Left
j::Down
k::Up
l::Right

Space::
    Loop, 8
    {
        Send, {Down}
        Send, {Down}
    }
    return

z::
    Send, {Up}
    return

+CapsLock::
CapsLock::Suspend, Off
CapsLock Up::Suspend, On
