How do I increase the 'View Orbit' amount? I would like to change the amount of degrees per orbit whenever I press the Numpad 4 or Numpad 6 keys from 15 to 22.5 degrees.

How would I do this?
The setting of the short cuts can be found in the user preferences, input tab.

Their names are 'view orbit'. The tricky thing is that the values needs to be in radians.

But you can use Python (transparently) to define the value you want in degrees. So to have 22.5 degrees, type "pi/8".



Now you can orbit with the wanted rotation :



Edit : you can also type "radians(22.5)". It seems all the math functions (math Python module, probably) are available.
