F4 is the keyboard shortcut for ORBIT.
However, you have to continually keep the key pressed while you are wanting to orbit.
How come the behavior is not the same as when you select ORBIT from the menu, where the cursor continually keeps you in ORBIT mode ?
Is there a way to obtain the same behavior ?
I use F4, you know "To each his own, what may be good for you may not be good for me !!!" Please re-read my original question. Can you answer the question that was asked ?
