You can use a letter instead of SPACE, you can use the 'Win' key (the code for this is #). Of course you can set your own combination: my example uses ^ (Ctrl), + (Shift) and SPACE (space bar). If you want to stop using the shortcut, you can close Autohotkey in the Windows notification area or pause the execution of the script from the menu.Run the script (just double click) and now when you hit Ctrl + Shift + Space in the active window, it will be displayed on top of other windows until the next time you hit the same key combination.On a new line in the script, type ^ + SPACE :: Winset, Alwaysontop, A.Give the script any name, then right-click on it and select 'Edit.'.In any folder or on the desktop with the context menu, select Create - AutoHotKey Script.Download and install AuthoHotKey from the official website.
