Rise or lift spawnpoints in ZE?

[Triops]

Hi, all!
I have an important question for a map I am "working" at:
How can I rise the nodes of spawnpoints in the zeroeditor. f.e. to spawn on the top of an object like a tower. I tried combinations of the C, X and Y-key with different mouse buttons, but without success. I would be logical for me if the middle mouse button and C key would work, but the middle mouse button seems to do nothing.
I would be very lucky, if somebody could help 


Edit: I have found the solution here at swbfgamers  . User "breakdown" wrote, that the right mouse button and the shift key are needed for rising spawn paths/ points. I havn't tried it now, but I think it will work with my map.

Excellent.  I remember doing it, but didn't remember how.

I also was wondering how to do it, but no way when I tried...
