Guide for combo outputs

[larry nelson]

Fred or anyone,

Is there a guide for new users on how to use combo output function.

Example; sip/puff combo L1+X or L1+X+X

Fighting games has multiple combinations to use and I would like to add some to my profile.

If you use a sip/puff for one input can you use it again as a combo with another output on the same sheet 

Thanks

Larry
