I have a term that I have coined the “Claw” while in Revit.  It relates to when a user is trying to move the end of a line based object (i.e. Grid, Wall, Beam) and they zoom in to find the grip and then while holding the mouse button, try to pan or zoom while using the middle mouse.  My tip is to drag that grip outside of the view window, for instance to the ribbon or properties pallet etc., and then release the mouse button.  The objects grip can now be moved without having to hold the mouse button down, hence allowing the user use their index finger to zoom or pan.  Once the objects grip is in the correct location click the mouse button to place it’s location.

This saves users from having to “Claw” their way through the file.
