This is a good reference for PostMessage stuff

but doesn't seem to have what you need on casual inspection.

 

Looks like you need

specifically the keybd_event function.

Pity, because this handy little script that I just wrote and tested seemed to do what you asked for in your original post :-(

#include <WinUser32.mqh>

// This script cycles between open chart windows using a CTRL+F6 keypress
int start(){
   for( int n=1; n<20; n++ ){
      Comment(n);
      keybd_event(17,0,0,0); // 17=Ctrl
      Sleep(10);
      keybd_event(117,0,0,0); // 117= F6
      Sleep(10);
      keybd_event(117,0,KEYEVENTF_KEYUP,0);
      Sleep(10);
      keybd_event(17,0,KEYEVENTF_KEYUP,0);
      Sleep(2000);
   }

My script does the same thing and has the same problem! (as noted in the referenced old post.) You have to catch whichever chart the script is running in and kill the script on that chart. Sounds like it needs a GlobalVariable as a flag to stop the script. Then a new Kill script can set the Global to a Kill value to kill off the slideshow script. The OP is only running once a minute, but at say 5 seconds per chart it could get a bit difficult to stop!
