Hi Danny, yeah if you want to do a whole bunch of 5 degree lines for a while, you can change the default snap angle using the Options screen Simon shows above - change the "Snap angle" under the "Straight snap options" area.

That will set the angle snap that is always active all the time. Then set that back to 90 when you are all done with the particular round of 5 degree snapping. That way you won't have to continuously enter in <5.
