Ok, I tried this. ISBoxer #35 already has CTM items under the keymap->general->"Click to move on" and "Click to move off" they are default to SHFT-ALT-N to turn it on,a nd CNTRL-ALT-N to turn it off. it uses a macro.
I replaced the default macro of /console AutoInteract 1 with your macros above. to debug it I also added to the right macro
/p click to move on
/p click to move off

I then made a new general mapped keys and called it "click to move onoff" and it sends SHFT-ALT-N to the main window and CNTRL-ALT-N to all of the other windows. then I made it so that each character get the "click to move onoff" mapped key pressed whenever they become the main.

it seems to be working fine and all of my toons say "click to move off" or "click to move on" ... twice but it still works. it did slow down the window switching slightly and that might be because it's sending the onoff key twice to every window.
