<title>Scrolling</title>
29
<p>You can use the scrollbars (located on the right and bottom of the timeline), use the mouse wheel anywhere over the timeline to scroll horizontally, or hold down the <key>Shift</key> key while using the mousewheel to scroll the timeline layers vertically.</p>
33
<title>Zooming</title>
34
<p>Zooming directly affects your editing accuracy and your ability to move quickly along the timeline:</p>
36
<item><p>When zooming in, video clips display more thumbnails and audio clips display increasingly detailed waveforms, allowing you to do precise edits.</p></item>
37
<item><p>Zooming out allows you to scroll faster along the timeline. Zoom can thus be used in conjunction with scrolling to move quickly between distant points of your project's chronology.</p></item>
39
<p>You can zoom in and out by holding the <key>Ctrl</key> key while using the mousewheel over the timeline, using the <guiseq><gui>View</gui><gui>Zoom In</gui></guiseq> and <guiseq><gui>View</gui><gui>Zoom Out</gui></guiseq>menu items, or dragging the zoom slider on the left of the ruler.</p>
41
<title><em>Warping</em> between zoom levels</title>
42
<p>Using your mouse's scroll wheel, you can also <em>warp</em> instantly from any zoom level to another in a single click. To do that, click with your mousewheel anywhere on the zoom slider.</p>
45
<p>To get a better overview of your timeline, you may use the <guiseq><gui>View</gui><gui>Best Fit</gui></guiseq> menu item or click the <gui>Zoom</gui> button on the left of the zoom slider.</p>

<title>Moving the playhead</title>
50
<p>You can change the position of the playhead by clicking anywhere on the ruler or on the timeline.</p>
51
<p>When clicking on the <em>timeline</em>:</p>
53
<item><p>If a clip is under the mouse cursor, it will replace the current clip selection (see the <link xref="selectmulti">Selecting multiple items</link> section for more detailed instructions).</p></item>
54
<item><p>If there is no clip under the cursor, all selected clips (if any) will be deselected.</p></item>
56
<p>When clicking on the ruler, only the playhead's position changes; clip selections are not affected.</p>
60
<title>Scrubbing</title>
61
<p><em>Scrubbing</em> is a way of moving the playhead that allows you to:</p>
63
<item><p>Search for a specific position in time by approximation/trial and error.</p></item>
64
<item><p>Review repeatedly the visual motion in a scene by moving back and forth in time.</p></item>
66
<p>To scrub, click on the ruler and move the mouse with the button still held down.</p>
67
<p>You can also scrub by dragging the black vertical line that stems from the playhead and spans across the timeline.</p>
