Customize Mouse Function

I’m coming to Rhino after years of Sketchup use. I’d prefer to retain native Sketchup mouse settings - scroll wheel zooms and rotates while secondary click provides context menu. Tools>Options>Mouse allows me to get the scroll wheel function I want, but I can’t get the context menu on the secondary button…am I missing something obvious?

Did you wait 250 milliseconds? A ‘list’ symbol will appear to the bottom right of the pointer when the required time has elapsed. And from a brief test here, the context menu delay under RMB also applies to the MMB.
