Is there any app to add a keyboard shortcut to a mouse click on a specific location? Basically I have a program that I use to study and I need to be able to quickly choose between a 8 choice answer button. The program does not have inbuilt keyboard shortcuts. I need to answer a question every 2 seconds so moving the mouse around gets tiring if I could just associate where the buttons are to 1-8 on the keyboard that would be great.
Try the TAB + Enter key. 
The TAB key should move the cursor to next question, the enter key should answer it.

Setting it up with 1-8 requires more doing, and you need to tell us what program are you using.
