64 <p>Inside this menu are 2 handy choices :</p>
68 <li><dfn>Selected tracks</dfn> that focus on the selected tracks. If the selected
70 tracks are not contiguous, the unselected tracks inbetween will be hidden, see
72 the <a href="/ardours-interface/editor-lists/tracks-and-busses-list/">Track and Bus list</a>.</li>
74 <li><dfn>All</dfn> that fits all the tracks of the sessions vertically (provided

82 <p>The rightmost buttons <kbd class="menu">Shrink tracks</kbd> and
84 <kbd class="menu">Expand tracks</kbd> reduce or expand the vertical size of the
86 selected tracks. If no track is selected, all the tracks will be shrunk or
88 expanded each time the button is pushed.
