Plug-in usually implement three basic controls: decrement value (), increment value (), and a main action ( or ). Plug-ins implement these commands, if pertinent, to maintain consistency across all plug-ins. Plug-ins are free to expand upon these controls by doing different things when modifier keys are held down, or by adding extra user interface elements that can be used by clicking the mouse.

Making a plug-in decrement it's value can be done by pressing the or by scrolling the mousewheel down when the cursor is over the mBezel window.

Making a plug-in inccrement it's value can be done by pressing the or by scrolling the mousewheel up when the cursor is over the mBezel window.

Examples of the incrementing or decrementing values for plug-ins:

• The Applications plug-in will show the next or previous application in the current list
• The Calendar plug-in will increment or decrement the current month by 1, or if the key is pressed it will increment or decrement the current year by 1.
• The Clipboard plug-in will select the next or previous clipboard slot
• The iTunes Remote plug-in will switch to the next or previous track in iTunes

Main actions for plug-ins are automatically mapped to and .

Examples of the the main actions for plug-ins are:

• The Applications plug-in will launch the currently displayed application
• The Calendar plug-in will return to the today's month
• The iTunes Remote plug-in will toggle iTunes current play status

Modifier keys can be held down when incrementing, decrementing, or when performing the main plug-in action. Each plug-in may or may not do different things when modifiers are pressed.
