By default, Ardour will show helpful <dfn>tooltips</dfn> about the purpose
|
|
and use of each <abbr title="Graphical User Interface">GUI</abbr> element if
|
|
the pointer is positioned over it and hovered there for a short while. These
|
|
little pop-up messages can be a good way to discover the purpose of many
|
|
aspects of the GUI.
|
|
</p>
|
|
|
|
<p>
|
|
Pop-ups can also be distracting for experienced users, who may wish to
|
|
disable them via <kbd class="optoff">Edit > Preferences > GUI > Show
|
|
tooltip if mouse hovers over a control</kbd>.

<h2>Selection Techniques</h2>
|
|
|
|
<p>
|
|
Ardour follows the conventions used by most other computer software
|
|
(including other DAWs) for <dfn>selecting objects</dfn> in the <abbr
|
|
title="Graphical User Interface">GUI</abbr>.
|
|
</p>
|
|
|
|
<h3>Selecting individual objects</h3>
|
|
|
|
<p>
|
|
Clicking on an object (sometimes on a particular part of its on-screen
|
|
representation) will select the object, and deselect other similar objects.
|
|
</p>
|
|
|
|
<h3>Selecting multiple (similar) objects</h3>
|
|
|
|
<p>
|
|
A <kbd class="mod1 mouse">left</kbd>-click on an object toggles its selected
|
|
status, so using <kbd class="mod1 mouse">left</kbd> on a series of objects
|
|
will select (or deselect) each one of them. A completely arbitrary set of
|
|
selections can be constructed with this technique.
|
|
</p>
|
|
|
|
<h3>Selecting a range of objects</h3>
|
|
|
|
<p>
|
|
In cases where the idea of "select all objects between this one and that one"
|
|
makes sense, select one object and then <kbd class="mod3
|
|
mouse">left</kbd>-click on another to select both of them as well as all objects in between.
|
|
</p>
|
|
|
|
<h3>Time range selection</h3>
|
|
|
|
<p>
|
|
To select a time <dfn>range</dfn> in the Editor, <kbd
|
|
class="mouse">Left</kbd>-click and drag the mouse. A <kbd class="mod1
|
|
mouse">Left</kbd> drag then lets you create other ranges and a <kbd
|
|
class="mod3 mouse">left</kbd>-click extends a range to cover a wider area.
|
|
</p>
|
|
|
|
<h3>Selection Undo</h3>
|
|
|
|
<p>
|
|
The set of objects (including time range) that are selected at any one time
|
|
is known as the selection. Each time an object is selected or deselected, the
|
|
new selection is stored in an undo/redo stack. This stack is cleared each
|
|
time the content of the timeline changes.
|
|
</p>
|
|
|
|
<p>
|
|
If a complex selection has been built up and then accidentally cleared it,
|
|
choosing <kbd class="menu">Edit > Undo Selection Change</kbd> will restore
|
|
the previous selection. If a selection is undone and a return to the state
|
|
before the undo is desired, choosing <kbd class="menu">Edit > Redo
|
|
Selection Change</kbd> will take the selection back to where it was before
|
|
<kbd class="menu">Edit > Undo Selection Change</kbd> was chosen.
|
|
</p>
|
|
|
|
<h2>Cut and Paste Operations</h2>
|
|
|
|
<p>
|
|
The <dfn>clipboard</dfn> is a holder for various kinds of objects (regions,
|
|
control events, plugins) that is used during <dfn>cut-and-paste
|
|
operations</dfn>.
|
|
</p>
|
|
|
|
<h3>Cut</h3>
|
|
|
|
<p>
|
|
A <dfn>cut</dfn> operation removes selected objects and places them in the
|
|
clipboard. The existing contents of the clipboard are overwriten. The default
|
|
key binding is <kbd class="mod1">x</kbd>.
|
|
</p>
|
|
|
|
<h3>Copy</h3>
|
|
|
|
<p>
|
|
A <dfn>copy</dfn> of the selected objects are placed in clipboard. There is
|
|
no effect on the selected objects themselves. The existing contents of the
|
|
clipboard are overwritten. The default key binding is <kbd
|
|
class="mod1">c</kbd>.
|
|
</p>
|
|
|
|
<h3>Paste</h3>
|
|
|
|
<p>
|
|
The current contents of the clipboard are <dfn>paste</dfn>d (inserted) into
|
|
the session, using the current <dfn>edit point</dfn> as the destination. The
|
|
contents of the clipboard remain unchanged—the same item can be pasted
|
|
multiple times. The default key binding is <kbd class="mod1">v</kbd>.
|
|
</p>
|
|
|
|
<h2>Deleting Objects</h2>
|
|
|
|
<p>
|
|
Within the Editor window (and to some extent within the Mixer window too),
|
|
there are several techniques for <dfn>deleting</dfn> objects (regions,
|
|
control points, and more).
|
|
</p>
|
|
|
|
<h3>Using the mouse and keyboard</h3>
|
|
|
|
<p>
|
|
Select the object(s) to be deleted and then press the <kbd>Del</kbd> key.
|
|
This does <strong>not</strong> put the deleted object(s) in the clipboard, so
|
|
they cannot be pasted elsewhere.
|
|
</p>
|
|
|
|
<h3>Using normal cut and paste shortcuts</h3>
|
|
|
|
<p>
|
|
Select the object(s) and then press <kbd class="mod1">x</kbd>. This puts the
|
|
deleted object(s) in the clipboard so that they can be pasted elsewhere.
|
|
</p>
|
|
|
|
<h3>Using just the mouse</h3>
|
|
|
|
<p>
|
|
By default, <kbd class="mouse">Shift Right</kbd> will delete the clicked-upon
|
|
object. Like the <kbd>Del</kbd> key, this does <strong>not</strong> put the
|
|
deleted object(s) in the clipboard.
|
|
</p>
|
|
|
|
<p class="note">
|
|
The modifier and mouse button used for this can be controlled via <kbd
|
|
class="menu">Edit > Preferences > User Interaction > Delete using
|
|
…</kbd>. Any modifier and mouse button combination can be used.
|
|
</p>
|
|
|
|
<h2>Undo/Redo for Editing</h2>
|
|
|
|
<p>
|
|
While editing, it sometimes happens that an unintended change is made, or a
|
|
choice is made that is later decided to be wrong. All changes to the
|
|
arrangement of session components (regions, control points) along the
|
|
timeline can be <dfn>undone</dfn> (and <dfn>redone</dfn> if necessary).
|
|
</p>
|
|
|
|
<p>
|
|
The default keybindings are <kbd class="mod1">Z</kbd> for Undo and <kbd
|
|
class="mod1">R</kbd> for Redo. These match the conventions of most other
|
|
applications that provide undo/redo.
|
|
</p>
|
|
|
|
<p>
|
|
Changes are also saved to the <dfn>session history</dfn> file, so that
|
|
undo/redo is possible even if the session is closed and reopened later, even
|
|
if Ardour is exited in between.
|
|
</p>
|
|
|
|
<p>
|
|
The maximum number of changes that can be undone can be configured under <kbd
|
|
class="menu">Edit > Preferences > Misc > Undo</kbd>. The maximum
|
|
number of changes stored in the history file is a separate parameter, and can
|
|
also be set in the same place.
|
|
</p>
|
|
|
|
<p class="note">
|
|
In addition to the normal undo (which works only on actions that change the
|
|
timeline), there is a <dfn>visual undo</dfn> which will revert any command
|
|
that affects the display of the editor window. Its shortcut is <kbd
|
|
class="mod3">Z</kbd>. There is also an undo for selection; see "Selection
|
|
Techniques" above.
