How does the main menu work?

Ok - trying to do something here that I know plucky knows how to do since he does it in SMM...

How exactly are items invoked from the main menu? I am messing around trying to add something to the Videos menu. I create a new "Item", in that item I set the ButtonText, and I copied "ThisItem" text from another working button. I also copied the AddStaticContect.. However, when I select my new button - nothing happens.

What I can't seem to find or figure out is what causes the transition from selecting that item to moving to the new screen/selection? In other words, where is the logic that takes you from "Browse By Folder" to the Brose-Videos component?

The green Action chain under an Item widget is the one that gets executed when the user selects that item. In your specific example of the "By Folders" item in the Video section of the Main Menu, that green Action widget is a comment that says "REM Jump to the video by Folders browser." Eventually, if you follow the reference links, that green chain terminates in a reference to the "Browser - Videos" menu.

Under an Item, any Action chain that doesn't terminate in a blue UI widget will be colored green. Although it's syntactically possible to have more than one such chain, only one of them will count as the "real" Action chain, so it's best to ensure that a given Item has at most one green child.

As a matter of style, I like to make that single green child a comment describing the action to be performed, with the actual code as children of that comment (i.e. grandchildren of the Item).

By the way, ThisItem is meant to be unique for each item. It's how the shared logic tells the items apart. So you don't want to be copying the ThisItem value from another item; you want to make up your own value that's different from all the others.

Cool - thanks... I wasn't fully understanding the linking aspects of "REM" type comment actions..

Yes you can make comments using quotes in a green action change. They are best preferenced with REM
