3 title: Selection Techniques
7 Ardour follows the conventions used by most other computer software
8 (including other DAWs) for <dfn>selecting objects</dfn> in the
9 <abbr title="Graphical User Interface">GUI</abbr>.
12 <h2>Selecting individual objects</h2>
14 Clicking on an object (sometimes on a particular part of its
15 on-screen representation) will select the object, and deselect other
19 <h2>Selecting multiple (similar) objects</h2>
21 A <kbd class="mod1 mouse">left</kbd> click on an object toggles its
22 <samp>selected</samp> status, so using <kbd class="mod1 mouse">left</kbd>
23 on a series of objects will select (or deselect) each one of them. You can
24 construct completely arbitrary selections with this technique.
27 <h2>Selecting a range of objects</h2>
29 In cases where the idea of "select all objects between this one and that
30 one" makes sense, you can select one object and then click
31 <kbd class="mod3 mouse">left</kbd> on another to select both of them as
32 well as all objects in between.
35 <h2>Time range selection</h2>
37 To select a time <dfn>range</dfn> in the Editor,
38 click <kbd class="mouse">Left</kbd> and drag the mouse.
39 A <kbd class="mod1 mouse">Left</kbd> drag then lets you create other
40 ranges and a <kbd class="mod3 mouse">left</kbd> click extends a range
41 to cover a wider area.
44 <h2>Selection Undo</h2>
46 The set of objects (including time range) that are selected at any one
47 time is known as the selection.
48 Each time you select or deselect an object, the new selection is stored in an
50 This stack is cleared each time the content of the timeline changes.
51 If you have built up a complex selection and then accidentally cleared it,
52 choosing <kbd class="menu">Edit > Undo Selection Change</kbd> will restore your
54 If you then decide that you had in fact made the correct change, choosing
55 <kbd class="menu">Edit > Redo Selection Change</kbd> will take you back
56 to where you were before you chose <kbd class="menu">Edit > Undo Selection Change</kbd>.
