Reversing the View

I’ve found the Num Pad keys 7, 1, and 3 useful for viewing a model from the top, front, and right side. However, to view from the bottom, back, etc., I have to press one of the rotation keys 12 times (using the default setting of 15 degrees). Is there any simpler way to switch, say, from a front view to a back view? (My workaround is to set the rotation angle to its max value of 90 degrees.)

Just use the Ctrl-key together with the NumPad Keys.
e.g. Ctrl+Numpad1 for the Backside etc.

You can also use Ctrl with the view selections in the 3D view window’s header.

Patel and pixelmass, thanks. That’s just what I needed.
