Right-click menus are a handy way to get to frequently-used commands. Depending on where you right-click (i.e. on a word in a word-processor, on a picture in a browser, on the desktop, or wherever else you think about), you will have a different assortment of commands in the right-click menu but what is common for all of them is that they are context-dependent and usually are the actions you are most likely to perform – i.e. if you select a word in MS Word and right-click, you will see options for copying it, cutting it, pasting it, applying formatting to it, etc. but if you right-click on an empty area of your desktop, you will get a different set of commands, like commands for arranging icons, for creating new folders, etc.

Most of the commands in right-click menus can be accessed from the main menubar or from the keyboard as well but right-clicking to get to them is much easier. And something else that even advanced users might not know is that right-drag is similar to right-click – it also opens a right-click menu.
