+<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.
+</p>
+
+<h2>Right Clicking</h2>
+<p>
+ The term <dfn>right-click</dfn> refers to the act of pressing and releasing
+ the <kbd class="mouse">Right</kbd> mouse button.
+ 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">
+ 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 <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">⇑</kbd> (ScrollUp) and
+ <kbd class="mouse">⇓</kbd> (ScrollDown). Some also emit horizontal
+ events, <kbd class="mouse">⇐</kbd> (ScrollLeft) and
+ <kbd class="mouse">⇒</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.
