Many of the commands in 3ds Max are available as buttons on various toolbars. By default, only the main toolbar is open, docked at the top of the interface.
Several additional toolbars are hidden by default, including Axis Constraints, Layers, Extras, Render Shortcuts, Brush Presets, and Snaps. To toggle a toolbar, right-click a blank area of the main toolbar and choose the toolbar's name from the list. See Customize Display Right-Click Menu for more information.
You can open and close toolbars and place them wherever you want; for more information, See Customizing 3ds Max.
