I was researching online to see if anyone had documented LDD Hollywood Edition, as someone who still loves LDD to this day, and wanted to share some info on LDD LEGOLAND because I've used it in the past.
LEGOLAND and Hollywood Edition builds are identical, the only difference being that with Hollywood you can export to Maya (as someone in this thread predicted).
Tool 1 is the classic grab tool, tool 2 is grab everything connected to the brick you're selecting, tool 3 is move (but more precise), 10 is freeze which is used in the "view" mode, 12 is group.
Wireframes show if you click on certain numbers, I think it goes up to 7? I forgot.
View mode is different, instead of having random skyboxes it's instead used to animate, it's very broken though.
Pallet bricks are grey automatically in extended mode.
Send to LEGO.com is still there, correct, but clicking it does nothing.
Brick count is a preference setting.
The logo for LDD LEGOLAND is a gold/yellow brick.
Models automatically save as lxfml instead of lxf.
If the programme crashes they autosave where your model left off so you can continue without restarting.
That's all I can think of from the top of my head! I wish I still had LDD LEGOLAND because it's much faster than the original software.
