title: Using the Mouse
---
+<h2>Clicking</h2>
+<p>
+ Throughout this manual, the term <dfn>click</dfn> refers to the act of pressing
+ and releasing the <kbd class="mouse">Left</kbd> mouse button. 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.

- <h2>Clicking</h2>
-<p>Throughout this manual, the term "click" refers to the act of pressing and releasing the leftmost mouse button (technically the button that is identified as button number 1 - your operating system may allow this be reassigned). This action is used to select objects, activate buttons, turn on/off choices, popup menus and so forth.</p>
-<p>On touch surfaces, it also corresponds to a regular, single-finger tap on the GUI.</p>
<h2>Right Clicking</h2>
-<p>Throughout this manual, the term "right-click" refers to the act of pressing and releasing the rightmost mouse button (technically the button that is identified as button number 3 - your operating system may allow this be reassigned). This action is used to pop up "context menus" (hence the term "context click", which you will also see). It is also used by default in combination with the shift key for deleting objects within the editor window.</p>

+<p class="note mac">
+ Some mice designed for use with Mac OS X may have only one button. By
+ convention, pressing and holding the Control key while clicking is
+ interpreted as a right-click by many application..
+</p>
+
+<h2>Middle Clicking</h2>
+<p>
+ A <dfn>middle-click</dfn> refers to the act of pressing and releasing the
+ <kbd class="mouse">Middle</kbd> mouse button. 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>
+<p class="note">
+ Internally, your operating system may identify the mouse buttons as
+ <kbd class="mouse">Button1</kbd>, <kbd class="mouse">Button2</kbd>, and
+ <kbd class="mouse">Button3</kbd>, respectively. It may be possible to
+ invert the order of buttons to accommodate left-handed users, or to re-assign
+ them arbitrarily. This manual assumes the canonical order.
+</p>
+
<h2>Double Clicking</h2>
-<p>A "double click" refers to two rapid press/release actions on the leftmost mouse button. The time interval between the two press/release 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>Drags</h2>
-<p>Throughut this manual, the term "drag" primarily refers to the act of pressing the leftmost mouse button, then moving the mouse with the button held down, and then releasing the button. On touch surfaces, this term also corresponds to a normal single finger touch-motion-release action.</p>
-<p>Ardour also uses the middle mouse button for certain kinds of drags, which will be referred to as "middle-drag" - these are identical to a normal drag except that they involve using the middle button rather than the left button.</p>
+<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.

+ A <dfn>drag</dfn> primarily refers to the act of pressing the leftmost

+ a single one-finger touch-move-release action.

+ 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 "modifier key". When the manual refers to Ctrl-click, it means that you should first press the Control key, then carry out a normal click while the Control key is held down, and then finally release the Control key. Available modifiers depend on the platform you are using Ardour on:</p>

<h3>Linux Modifiers</h3>
<ul>
-<li>Control (Ctrl)
-</li>
-<li>Shift</li>
-<li>Alt</li>
-<li>Mod2</li>
-<li>Mod3</li>
-<li>Mod4</li>
-<li>Mod5</li>

+ <li><kbd>Mod2</kbd></li>
+ <li><kbd>Mod3</kbd></li>
+ <li><kbd>Mod4</kbd></li>
+ <li><kbd>Mod5</kbd></li>
</ul>
-<p>Mod2 typically correspond to the NumLock 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 xmodmap(1). This can be rather useful.</p>

-<h2>Mouse Wheel/Scroll</h2>
-<p>Ardour can make good use of a scroll wheel on your mouse, which can be utilized for a variety of purposes. Scroll wheels can generate both vertical scroll events (ScrollUp and ScrollDown) and/or horizontal events (ScrollLeft and ScrollRight). 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, scrolling is used to adjust continuous controls (e.g. faders/knobs), or to scroll vertically or horizontally.</p>
