Hotkeys [1;2;3 + Mousedrag] possible for Pan;Zoom;Rotate ?

Hello,

is it possible to create shortcuts/hotkeys for

Pan = [1 + Mouse drag]
Zoom = [2 + Mouse drag Up/Down]
Rotate = [3 + Mouse drag]

Because I have big hands and a small keyboard and it's a bit uncomfortable for me to use ALT/CTRL/SHIFT all the time. I am using CInema4D and Pan/Zoom/Rotate is possible with 1;2;3+ Mouse and it's much better for me.

Thank you very much in advance and I fell in love with this software!:)
