11 <p>The zoom controls allow to navigate the session along both the time and track axes.</p>
15 <p>The drop down <kbd class="menu">Zoom Focus</kbd> menu allows to select a focus
17 point for the zoom, i.e. the center of the zoom. The choices are :</p>
23 <li><dfn>Left</dfn> of the screen</li>
25 <li><dfn>Right</dfn> of the screen</li>
27 <li><dfn>Center</dfn> of the screen</li>
29 <li><dfn>Playhead</dfn></li>
31 <li><dfn>Mouse</dfn></li>
33 <li><dfn>Edit Point</dfn> as set in the <a href="/ardours-interface/the-editor/the-toolbar/the-edit-point-control/">Edit point</a> control.</li>
39 <p>The 2 leftmost zoom buttons (<kbd class="menu">−</kbd> and
41 <kbd class="menu">+</kbd>) use this zoom focus to zoom out and in
47 <p>The <kbd class="menu">Zoom to session</kbd> button is a handy shortcut to zoom
49 out or in until all the session (as defined by it's <a href="/working-with-markers/">start/end
51 markers</a>) fits horizontally.</p>
55 <p>Changing the <kbd class="menu">Number of visible tracks</kbd> dropdown menu
57 allows to fit this number of tracks vertically in the screen.<p>
61 <p class="note">There <em>is</em> a minimal track height to keep it visible, so
63 according to you screen vertical size, some high number can have no effect.</p>
67 <p>Inside this menu are 2 handy choices :</p>
71 <li><dfn>Selected tracks</dfn> that focus on the selected tracks. If the selected
73 tracks are not contiguous, the unselected tracks inbetween will be hidden, see
75 the <a href="/ardours-interface/the-editor/the-editor_s-lists/tracks-and-busses-list/">Track and Bus list</a>.</li>
77 <li><dfn>All</dfn> that fits all the tracks of the sessions vertically (provided
79 there's enough screen estate).</li>
85 <p>The rightmost buttons <kbd class="menu">Shrink tracks</kbd> and
87 <kbd class="menu">Expand tracks</kbd> reduce or expand the vertical size of the
89 selected tracks. If no track is selected, all the tracks will be shrunk or
91 expanded each time the button is pushed.
