Graph Editor custom controls ?

I’m using a tablet and not happy with the controls. I use Blender a lot and that’s set to maya controls so I use the “alt” key a lot, in the graph editor panning is “cmd + rmb”, I’d like to swap it. Zooming in and out seems a bit buggy using the tablet not sure why but I can stick to hotkeys for that. Also to bring up the reference popup menu is using “rmb” but can’t find the hotkey for that ?

Got it slightly wrong, I don’t need to hold “cmd” whilst “rmb” to pan. Also found holding “rmb” whilst “lmb” up / down zooms in & out.
