Simulate wireless keypad

Good afternoon,

I need to simulate two keys on the keyboard to trigger a software, I have a TV in my shop and software that switches the screen with ALT + 9 and around the screen with ALT + 4, the TV is far and do not want in a keyboard without wire to use only two keys, so need (and want) to create a button bluetooth, wiFi or RF to simulate the keyboard and switch the screens.

I researched a lot and found nothing. I found a button RF transmitter and recepitor but do not know how to simulate the keyboard.

Thank you.
