how to bind Mame Gui to a hotkey combination

Hello all,
I try without success to bind the MAME Gui (normally TAB) to a hotkey combination on my bartop. I'm using the LR-MAME-2003+ core.
Searched on the forum, but cannot find anything.
I'm using GPIO connected buttons.

I have already bind my "volume+" & "volume-" to hotkey + L & R keys.
by adding following lines in my retroarch autoconfig gpio P1 file :
input_volume_up_btn = "4"
input_volume_down_btn = "5"

Now, try to do the same for the "tab" key ?

Any ideas ?

Thanks

@carlhungus74 I think that MAME gui for libretro cores can be turned on and off through an option in the retroarch menu.

@saccublenda Thanks. Any idea where this option could be ? Navigated in all RGUI without success for now ?

I think @saccublenda is thinking of the Core Option to show the Mame menu.
You can bring up the MAME menu also by pressing the RetroPad RT button (Right Trigger) in RetroArch.

@carlhungus74 It is in
Main menu -> Quick Menu -> Options -> Display MAME menu
I don't know if it can be bound to an hotkey though.

Ok found it. But it's pretty "long" to go the option / put it "on", change some settings, go back to the RGUI, put it "off" to hide it. Hope I could find a way more convenient ?

@mitu I don't have RT button on my bartop (only 6 buttons for each player (+ start/select). That's why I try to map it on a hotkey.

Since I mainly use libretro cores I don't use the mame gui that much anymore, except for some dip switch settings. For all others settings I want to change I use the retroarch menu.

Yes, don't use everytime also, only to access the "cheat" menu of Mame, for kids plays.
I don't think the "cheat" menu of RGUI is similar for Mame.

@carlhungus74 OK, I've found something.
If you go in Main menu -> Quick Menu -> Options and set Input interface to mame_keyboard or simultaneous you can use the keyboard tab key to bring up the MAME menu, old style.

@saccublenda Thanks. Don't have a keyboard plugged on my bartop so I will use the Quick menu / options solutions...I can live with that.

Thanks.
