[Solved]hard exit, suitable for Steam Link setup?

[Hubble128]

Greetings, everyone! I've just discovered this wonderful emulator, and thrilled that I can set up my old games in full HD size on my home theater instead of the small format that I had to put up with using the analog output cables from my old PSP.

I do have a question - relating to exit commands. I have looked over the FAQ and beginner guides and cannot seem to find an answer, but I apologize if it is there and I just missed it.

I am using the emulator on a PC that feeds a Steam Link in my home theater. I have a few other emulators running successfully on this setup, and they both have a "-nogui" command line switch that I can use so that a simple press of the escape key ends emulation and kicks me back to Steam's menu system.

Is there an equivalent in PPSSPP? Either a command line switch or a setting or an INI file parameter that could be used to create this kind of "hard exit"?

Many thanks in advance!
