Roger, Welcome to the fun world of emulation, where everyone knows the information you want yet no one can give you the information you need. We were all new once. As much as you dont like to read "google" is your friend. It really is the best start. So, you played Gorf.. An older amusing game. I had it for my VIC20.. Anyways I am assuming your are playing it in MAME. Mames default keys are Ctrl and Alt for buttons 1 and 2. That should get your space fighter shooting. Gameex is a front end and has little to do with the emulation it self. So please take the time to familiarize yourself with the emulators you are choosing to use. Emulators, are written by different people, some are discontinued some are not, some older ones work better than newer ones. Some games simply do not work with certain emulators. Gameex has the ability to "group" emulators together. So if you have a few rouge games that work better in a different emulator. you can group the two together, for a seamless presentation. MAME, is the best (most compatible) arcade emulator. Sure there are others, but... It would be a hassle to go through the many variants of arcade emulators. In my opinion you would use Mame for all but Naomi and Atomis wave systems.
