FYI; RetroArch / Lakka uses "Select+X" on gamepads and "F1" on keyboard as default hotkeys combinations to bring up RGUI (RetroArch's equivalent to in-game OSD):

EmulationStation / RetroPie uses the same "Select+X" combo on gamepads and "F1" as hotkey on keyboard for the same action to bring up its emulator in-game OSD:

Hotkeys

Hotkeys enable you to press a combination of buttons to access functions such as saving, loading, and exiting emulators. The following chart shows the default hotkey combinations. By default, the hotkey is select so that means you hold down select while pressing another button to execute a command. Note that hotkeys are only specific to the retroarch/libretro based emulators.

Hotkeys Action
Select+Start = Exit
Select+Right Shoulder = Save
Select+Left Shoulder = Load
Select+Right = Input State Slot Increase
Select+Left = Input State Slot Decrease
Select+X = RGUI Menu
Select+B = Reset
