Did you download the new release? The previous version had broken buttons.
I believe the ARM link on the home page now downloads the current working version as well. Try redownloading.

This is the key that you hit to change an entry in the MameUI. (equivalent to the Enter key in Destop Mame).

Yes 1 is the Home key which desn't work at all.

Hope that clarifies things.
