How to edit a fillet radius in a sketch?

I added a fillet to a previously sharp corner. I later wished to change the fillet radius to a specific value. I can change the radius by dragging one of the endpoints, but I want to specify the value numerically. How can do this?

When you create the sketch fillet it should have a dimension attached to it:
You can drag this dimension around to reposition it (it may initially be behind the fillet), and double click on it to edit the value. The 'R' indicates that this is a dimension for the radius of the fillet.
Let us know if you're still having trouble.Jake Rosenfeld - Modeling Team5 -

Sigh...
I SWEAR that I tried this. Of course, when I tried it just now, it worked like a champ. Go figure.
Thanks!1 -

Beware there are important subtleties to using the 2D Fillet tool to create fillets. If you select two curve segments to fillet, a radius dimensional constraint (w/tangent constraints) will a be uniquely created for that fillet. However, if you select a series of points where two curve segment meet, then only the first fillet gets a radius dimensional constraint. The other fillet locations get a "equal" constraint created between its arc/fillet to the arc/fillet with the radius constraint.
Understanding what the 2D fillet does (at the constraint level) is important when you need to modify the sketch constraint scheme to either decouple, or couple fillets in the sketch.5
