+<p>
+ <dfn>Keyboard bindings</dfn> are shown like this: <kbd>s</kbd> or
+ <kbd class="mod1">x</kbd>.
+</p>
+<p>
+ <kbd>Ctrl x</kbd> means "press the <kbd>Ctrl</kbd> key, keep it pressed
+ and then also press the <kbd>x</kbd> key.
+</p>
+<p>
+ You may also see key combinations
+ such as <kbd class="mod12">e</kbd>, which mean that you should hold down
+ the <kbd class="mod1"> </kbd> key <em>and</em> the
+ <kbd class="mod2"> </kbd> key, and then, while keeping them both
+ down, press the <kbd>e</kbd> key.
+</p>
+<p>
+ Note that different platforms have different conventions for which
+ modifier key (Control or Command) to use as the primary or most common
+ modifier. When viewing this manual from a machine identifying itself as
+ running OS X, you will see <kbd>Cmd </kbd> where appropriate (for instance
+ in the first example above). On other machines you will see <kbd>Ctrl </kbd>
+ instead.

+
+<h3>Mouse Buttons</h3>
+<p>
+ We refer to <a href="/setting-up-your-system/the-mouse">mouse buttons</a> as
+ <kbd class="mouse">Left</kbd>, <kbd class="mouse">Middle</kbd> and
+ <kbd class="mouse">Right</kbd>. Ardour can use additional buttons, but they have
+ no default behaviour in the program.
+</p>
+
+<h4>Mouse click modifiers</h4>
+<p>
+ Many editing functions are performed by clicking the mouse while holding a
+ modifier key, for example <kbd class="mouse mod1">Left</kbd>.
+</p>
+
+<h4>"Context-click"</h4>
+<p>
+ Many times the term <kbd class="mouse">context-click</kbd> is used to indicate
+ that you should (typically) right-click on a particular element of the graphical
+ user interface. Although right-click is the common, default way to do this, there
+ are other ways to accomplish the same thing - this term refers to any of them,
+ and the result is always that a menu specific to the item you clicked on will be
+ displayed.
+</p>
+
+<h4>"The Pointer"</h4>
+<p>
+ When the manual refers to the "pointer", it means the on-screen representation
+ of the mouse position or the location of a touch action if you are using a touch
+ interface.
+</p>
+
+<h3>Other user input</h3>
+<p>
+ Ardour supports hardware controllers, such as banks of
+ <kbd class="fader">faders</kbd>, <kbd class="knob">knobs</kbd>, or
+ <kbd class="button">buttons</kbd>.
