How to spin object/view around axis perpendicular to screen?

I know - it can be done by highlighting the Free Orbit icon at the bottom of screen and by grabbing the circle that appears on the screen. But boy, is this slow and cumbersome! Great for a novice who designs with the speed of a turtle... I cannot be looking for that icon and activating it like... 60 times a minute.

There must be a key that I don't know about? Which key is that?

Or perhaps there is a simpler/faster way... ?

Not sure I understand but have you tried the "Look At" icon next to the orbit icon at the bottom of the screen?  Click on what you want to look at straight on and then click the icon. The perspective will spin around so you're looking straight at it.
