Command + A + Click

Hello all,

I'm stumped and can't figure out how to execute Command+A+Click at the same time.
I attempted to use some applescript and Karabiner elements, but I can't seem to get it to work properly. Anyone have suggestions?

I found a workaround...
I created a macro that runs an AppleScript that calls another KM macro....
But does anyone else have an easier way?

tell application "System Events"
    key down {command}
    key down "a"
    tell application "Keyboard Maestro Engine"
        do script "ZZZ Click at current"
    end tell
    key up {command}
   key up "a"
end tell

The ZZZ Click at current macro is solely a click at current location.
