How do you lift top in trunk

This might be a very silly question...but a search of the internet and this site have failed me.

Can someone tell me how do I get the Targus top to lift while it's locked in place in the trunk.

I've had my car for 2 years now and discovered this feature by accident one day when it lifted by itself one day. Previous to that...I would always unlock it from the harness in order to access the trunk space.

Thanks for any help!!!

put your hand between the targa and the rear trunk wall
move it down
find the lever
pull the lever

THANKS!! Found it!
