<p>
Navigating the Editor window is obviously a very frequent operation. Ardour sticks
with a lot of the usual conventions in this regard, to allow for a quick learning.
As those operations are so common, it is worth taking the time to learn most of
the keyboard and mouse shortcuts in order for these to become fast and natural.
</p>
<p>
The keyboard shortcuts can, as always, be edited, so the defaults are shown here.

<h2>Scrolling</h2>
2017-04-10 08:52:14 -04:00
<p>
2017-04-10 09:55:27 -04:00
Scrolling can be done on-canvas, or with the <a href="@@summary">Summary</a>.
2017-04-10 08:52:14 -04:00

<p class="note">
Moving the playhead outside the view may scroll the screen accordingly, so using
2017-04-18 04:12:52 -04:00
<kbd class="mod2">&larr;</kbd> or <kbd class="mod2">&rarr;</kbd>, while not
<em>scrolling</em> per se, will result in scrolling if <kbd class="option">Transport &gt; Follow playhead</kbd>
is checked. This is also true with the <a href="@@mini-timeline">
2017-04-10 08:52:14 -04:00
Navigation Timeline</a>, and anything that moves the Playhead.
</p>
<h3>In the Summary</h3>
<p>
2017-04-10 09:55:27 -04:00
Clicking and dragging in the Summary will scroll the view left and right. If the
screen view is clicked (the white rectangle) and dragged, the view can also be scrolled
2017-04-10 08:52:14 -04:00
vertically.
</p>
<p>
2017-02-14 10:20:06 -05:00
Additionally, on the left of the Summary, the two <kbd class="menu">&lt;</kbd> and
2017-04-10 08:52:14 -04:00
<kbd class="menu">&gt;</kbd> arrows buttons allow to scroll one screen either left
or right, while at the right of the Summary, the two <kbd class="menu">&and;</kbd> and
<kbd class="menu">&or;</kbd> arrows buttons allow to scroll one screen either up
or down.
</p>
<h2>Zooming</h2>
<p>
2017-04-21 05:33:31 -04:00
Zooming (on time) can be done on-canvas (which will always be centered around the mouse cursor),
2017-04-10 08:52:14 -04:00
with the Summary, or with the <a href="@@zoom-controls">Zoom Controls</a>.
</p>
<h3>On Canvas</h3>
<table class="dl">
<tr><th>Zooming in</th><td><kbd class="mod1 mouse">&uArr;</kbd></td></tr>
<tr><th>Zooming out</th><td><kbd class="mod1 mouse">&dArr;</kbd></td></tr>
</table>
<h3>In the Summary</h3>
<p>
Resizing the screen view in the Summary (the white rectangle) changes the zoom
accordingly.
</p>
<h3>With the Zoom Controls</h3>
<p>
With the Zoom Focus set, the <kbd>&minus;</kbd> and <kbd>&plus;</kbd> buttons
will zoom out or in around this focus. The <kbd>[&nbsp;]</kbd> button zooms to the
whole session as defined by the start and end markers.
</p>
<p>
Theses controls are bound to the keyboard <kbd>&minus;</kbd> and <kbd>=</kbd>
respectively by default.
</p>
<h2>Height of the tracks</h2>
<p>
Changing the height of the tracks results in more or less tracks on screen. This
can be done on canvas, with the Summary or with the Zoom Controls.
</p>
<h3>On canvas</h3>
<p>
Using <kbd class="mod2 mouse">&dArr;</kbd> or <kbd class="mod2 mouse">&uArr;</kbd>
while hovering over a track reduces or enhances its height, i.e. zooms on the
hovered track, regardless of the selection.
</p>
<p>
The <kbd>F</kbd> key resizes the tracks so that only the selected one(s) are
2017-02-14 10:20:06 -05:00
displayed. If some unselected tracks are in-between those selected tracks, their
2017-04-10 08:52:14 -04:00
<a href="@@the-tracks-and-busses-list">visibility</a> will be toggled off.
</p>
<h3>In the Summary</h3>
<p>
Resizing the screen view in the Summary (the white rectangle) changes the number
of tracks displayed (hence their heights) accordingly. It behaves more like a zoom
as the relative height of the tracks are kept.
</p>
<h3>With the Zoom Controls</h3>
<p>
The three rightmost buttons of the Zoom Control bar, while not zoom buttons,
act upon the height of the tracks:
</p>
<ul>
<li>The first selector directly selects how many tracks are currently on screen.</li>
<li>The second one reduces the height of the selected track(s). If none are
selected, all the tracks are affected, while maintaining (as long as it is
possible) their relative heights.</li>
<li>The third one enlarges the tracks, and is the counterpart of the previous
one.</li>
</ul>
