Hi guys, I am pretty new to AHK, but I did RTFM, but still can't figure out how to do it. In my editor, or any other app that has multiple documents, I would like to be able to maximize/restore the active child document window. It works fine with the main app: WinGet, x, MinMax, A If x = 1 WinRestore, A else WinMaximize, A But how do I do it with the child window? TIA, Björn
