Keeping ALL open apps awake?

Hey all,
While the mouse/keyboard "jigglers" work to keep Windows awake, I am looking for a way to also keep my open applications awake.  Say every minute or every x minutes it would send a mouse or F15 command to any open program.  This probably means I would see a brief interruption in whatever program I happened to be using, but that wouldn't be a problem.   Does anyone know of such a program?  Again this is for Windows 10.

Thanks.

I would write a script in ahk :   https://www.autohotkey.com
Timed sending keys to an app is only a few lines of code and there is a very helpfull ahk forum to ask questions.

AHK is free to use and updating thanks to active members.

sending F3 to notepad every minute looks like this :





#persistent
SetTitleMatchMode , 2
SetTimer,send_it, 60000                    ; this is one minute 60*1000 msec
return

send_it:
ControlSend ,,{F3}, Notepad             ; windowtitles are case sensitive !!
return
