<h2>Clicking</h2>
<p>
Throughout this manual, the term <dfn>click</dfn> refers to the act of pressing
and releasing the leftmost mouse button (technically identified as
<kbd class="mouse">Button1</kbd>, but your operating system may allow
this to be reassigned). This action is used to select objects, activate
buttons, turn choices on and off, pop up menus and so forth.<br />
On touch surfaces, it also corresponds to a single, one-finger tap on
the GUI.
</p>
<h2>Right Clicking</h2>
<p>
The term <dfn>right-click</dfn> refers to the act of pressing and releasing
the rightmost mouse button (internally called <kbd class="mouse">Button2</kbd>,
but again your operating system may allow this to be reassigned).
This action is used to pop up <dfn>context menus</dfn> (hence the term
"context click", which you will also see). It is also used by default in
combination with the shift key to delete objects within the editor
window.
</p>
<p class="note mac">
Mac OS mice sometimes have only one button. On Mac OS if you press and hold
the Control key this is equivalent to right-clicking.
</p>
<h2>Middle Clicking</h2>
<p>
A <dfn>middle-click</dfn> refers to the act of pressing and releasing the
middle mouse button (<kbd class="mouse">Button3</kbd>, which may also be
reassigned). Not all all mice have a middle click button
(see the <a href="/setting-up-your-system/mouse/">Mouse</a> chapter for
details). Sometimes the scroll wheel acts as a clickable middle button.
This action is used for time-constrained region copying and mapping MIDI
bindings.
</p>
<h2>Double Clicking</h2>
<p>
A <dfn>double click</dfn> refers to two rapid press/release cycles on the
leftmost mouse button. The time interval between the two actions that
determines whether this is seen as two clicks or one double click is
controlled by your system preferences, not by Ardour.
</p>
<h2>Dragging</h2>
<p>
A <dfn>drag</dfn> primarily refers to the act of pressing the leftmost
mouse button, moving the mouse with the button held down, and then
releasing the button. On touch surfaces, this term also corresponds to
a single one-finger touch-move-release action.
</p>
<p>
Ardour also uses the middle mouse button for certain kinds of drags,
which will be referred to as <dfn>middle-drag</dfn>.
</p>
<h2>Modifiers</h2>
<p>
There are many actions in Ardour that can be carried out using a mouse
button in combination with a <dfn>modifier key</dfn>. When the manual
refers to <kbd class="mod1 mouse">Left</kbd>, it means that you should first
press the <kbd class="mod1"></kbd> key, carry out a left click
while <kbd class="mod1"></kbd> is held down, and then finally release the key.
</p>
<p>
Available modifiers depend on your platform:
</p>
<h3>Linux Modifiers</h3>
<ul>
<li><kbd>Ctrl</kbd> (Control)</li>
<li><kbd>Shift</kbd></li>
<li><kbd>Alt</kbd></li>
<li><kbd>Mod2</kbd></li>
<li><kbd>Mod3</kbd></li>
<li><kbd>Mod4</kbd></li>
<li><kbd>Mod5</kbd></li>
</ul>
<p class="warning">
The following section is almost certainly wrong. Will need to be checked
and rewritten asap.
</p>
<p>
Mod2 typically corresponds to the <kbd>NumLock</kbd> key on many systems.
On most Linux systems, there are no keys that will function as modifiers
Mod3, Mod4 or Mod5 by default, but they can be setup using
<dfn>xmodmap(1)</dfn>. This can be rather useful.
</p>
<h3>OS X Modifiers</h3>
<ul>
<li><kbd>Cmd</kbd> (Command, "windmill")</li>
<li><kbd>Ctrl</kbd> (Control)</li>
<li><kbd>Alt</kbd> (Option)</li>
<li><kbd>Shift</kbd></li>
</ul>
<h2>Scroll Wheel</h2>
<p>
Ardour can make good use of a <dfn>scroll wheel</dfn> on your mouse, which can be
utilized for a variety of purposes. Scroll wheels generate vertical
scroll events, <kbd class="mouse">&uArr;</kbd> (ScrollUp) and
<kbd class="mouse">&dArr;</kbd> (ScrollDown). Some also emit horizontal
events, <kbd class="mouse">&lArr;</kbd> (ScrollLeft) and
<kbd class="mouse">&rArr;</kbd> (ScrollRight).
</p>
<p>
When appropriate, Ardour will differentiate between these two different
scroll axes. Otherwise it will interpret ScrollDown and ScrollLeft as
equivalent and similarly interpret ScrollUp and ScrollRight as equivalent.
</p>
<p>
Typically, scroll wheel input is used to adjust
<dfn>continuous controls</dfn> such as faders and knobs, or to scroll
vertically or horizontally inside a window.
