Hi, Michael.

In the Moi Wiki, the hotkeys section, it says:
1) On a scene browser color swatch, Ctrl+Shift+Left click will assign the selection to that style without altering the visibility or locked state of the objects to match the current style.
2) Clicking on the name part of a scene browser item is used for selection, if you hold down Ctrl while clicking on it it will work for deselection instead of selection,
and if you hold down Shift while clicking on it it will only select currently visible objects instead of selecting and showing all objects that belong to that slot.

Does not work. Or do I not understand something?
