[How to do instruction] Use hardware momentary switches to control moOde

[sisim]

In GPIO Config does the line below appear under the SAVE button?

"NOTE: Use a comma to delimit arguments in the CMD field. Example: mpc,load,My Playlist"

Hello Tim, thank you so much for your quick reply, and congratulation again for your work!!

No, this line does not appear under the SAVE button. I tried though (mpc,stop) and it doesn't work either. Any other idea?
