Some settings in the options bar are common to several tools (such as painting modes and optically) and some are specific to one tool (such as the Auto Erase setting for the pencil tool).

You can move the options bar anywhere in the work area, or dock it at the top or bottom of the screen. if you'd like to move the options bar, click on the small line on the far left of the toolbar and drag it to a new position.

The options bar includes a palette well to the right, for storing other palettes, providing quick access to palettes such as Swatches and Actions that you reference briefly while using the application. The palettes well is only available when using a screen resolution great then 800 pixels x 600 pixels (a setting of at least 1024x768 is recommended).
