[LE] Any way to raise/lower navmesh vertices other than "f" key?

[kevkiev]

I'm a beginner at NM, but searched a lot on the 'net and couldn't find anything. Would be nice if NM vertices could be manipulated along their z-axis like you can a "normal" object in the CK. Even with all objects hidden (or in navmesh-only view), hitting "f" results in some of my slightly-too-high vertices jumping upwards even more. What's the best way to do that when the F key isn't cooperating?

 

Alternatively Is there a way to see a vertex's z-axis value somewhere such that you could manually input a number? Again, like a physical object. E.G. Would be a god send to be able to see the z-axis values for the level vertices, then be able to input that value for the stubborn vertices.

Hold the Z key and drag. That locks movement into the Z axis (up/down).

Thanks very much.
