You can quickly access many of your most commonly used tools with marking menus.
Marking menus are used throughout the Maya interface.
When you 
an object,
a marking menu appears that lets you select a selection mode and
other options. Some marking menus appear when you hold a key and
press a mouse button.
Marking menus are very fast for experienced users because once you get used to showing them and the positions of their items, you can select the items using very quick gestures with the mouse or tablet pen, sometimes so fast the entire menu won’t even display.
