I've known about the 'previous view' command for years, but never really used it. A trip to my swxjrnl file recently made me aware of just how much time I spend rotating and zooming parts in the work window. Observing myself work taught me that a lot of that view manipulation was zooming in tight, rotating the view a little so I could pick something, then going through a convoluted process to get back to the original, tight view.
Of course CTRL+SHIFT+Z will return to the previous view, so I've made a concerted effort to force myself to use it. And I'm glad I did - I must hit it a hundred times a day.
The other view command that I use dozens of times a day is SHIFT+arrow keys for rotating the model 90 deg. Boy that one is handy (when a 'normal to' comes in the wrong direction or orientation, etc).
