Time Ruler

Hello All -

This may be simple and I am just missing it. My time ruler is set up for the measures and beats. When I expand a bit with the zoom I get 3 lines between each number. SO 4 beats a measure..thus 4/4. How can I change this for a tune in 3/4 so I see 1 | | 2 | | 3 | | etc...

Thanks

Nevermind...I found the meter change option in the insert menu.
