how I wanna set up my g700s and g510s. all these extra buttons and options and stuff are awesome but I don't really know

I got g3 set to thelegendaryfjscrew@gmail.com and when I launch second life the g7 to g12 keys are set as the f3 to f8 keys for CCS, and right now I only have one active profile on my mouse and the g5 and g4 are volume g6 and g7 are dpi and g10 and g9 are forward/back even though I pretty much never need that
