¿How to add new key?

[AdriJoker]

Hello

I downloaded today the emulator for Android plus something called pspkvn that allows me to play java games. It works perfectly. I was testing a game that asks me to press the * key. This is not among the touch controls. I went to game settings but modification of controls is not available. Then I went to the configuration of the emulator but I can not see any option that allows me to add the asterisk key as control ... Any ideas?

Thank you
