I'm trying to learn to write my first tool, using other people's tools as a reference as well as the docs. I want to add a slider and the docs tell me to "see the "UI: Controls" section of the Command List by Function. " This is where I feel very stupid, but I cannot find a section in the docs called "Command List by Function". I searched all throughout, but nothing! I searched the MEL Command reference, but there is nothing in there about UI: Controls either. Help?!? Thanks.
