There is an 'Inbetweening' section on an objects waypoint tab. The inbetweening section has a number of options...
a. A textbox for puting in 'number of waypoints.
b. An option for before & after current waypoint.
c. A tickbox for 'interpolate altitude'.
d. A tickbox for 'interpolate speed'.
e. A tickbox for 'carry over type'.
f. A button for 'Create'
Can anyone shed any light what the 'inbetweening' section is for?
[EDIT] - Never mind, I figured it out
