> Using the Editor Window’s Toolbar
> Below the canvas is a toolbar. It displays several tools you’ll use to configure your canvas, preview your video, and monitor your audio, as described below, in Table 4.

> Table 4. Using the Editor Window Toolbar
> Control | Description
> Canvas Button | Click the canvas button (far left) to display the canvas controls—click it again to hide them. You can use these controls to view and adjust canvas properties: the canvas size (and resulting frame size of your exported video) and background color. For details, see Configuring the Canvas.
> Playback Controls | Use the playback controls (center) to play your project as well as jump to the beginning or end of your project. You can also use the traditional video editor’s JKL keystrokes for Rewind, Stop, and Playback. Press J or L repeatedly to speed up rewind/playback respectively. The timecode of the project is displayed directly to the right of the playback controls. (You can set timecode to SMPTE or ScreenFlow—see Timeline Pane.)
> Audio Meter | The audio meter (far right) displays audio volume. The top meter represents the left channel; the bottom, the right channel.
