Views menu > Expert Mode
Keyboard > CTRL+X
When Expert Mode is on, the menu bar, toolbar, tab panel, command panel, status bar, and all of the viewport navigation buttons are removed from the display, leaving only the title bar, time slider, viewports, and any custom floaters. Use Expert Mode when you need to view your composition alone without the rest of the gmax interface.
With the ability to customize the user interface in the software you can create your own versions of Expert Mode by hiding whatever you want on an item-by-item basis. Expert Mode is only a quick way to hide everything that can be hidden at once.
When in Expert Mode use Keyboard Shortcuts to hide and unhide the command panel, toolbars and so on. You can use the quad menu to access tools quickly in Expert mode, as well.
