The radial menu is a circular grouping of commands that displays around your cursor when you press 5 on the numeric keypad while the cursor is over a graphic view. You decide which commands are included in the menu by using the options on the Customizations Tab (Options Dialog).
You can define up to eight commands to display on your radial menu. You can click the icons, or press the key on the numeric keypad that corresponds with the location of the command on the radial menu. For example, to run the Fit command you would press 5 and then 9. Press ESC to exit the radial menu without starting a command.
In the center of the radial menu is the command you used last. Press 5 on the numeric keypad to start this command again.
