8 Throughout this manual, the term <dfn>click</dfn> refers to the act of pressing
9 and releasing the leftmost mouse button (technically identified as
10 <kbd class="mouse">Button1</kbd>, but your operating system may allow
11 this to be reassigned). This action is used to select objects, activate
12 buttons, turn choices on and off, pop up menus and so forth.<br />
13 On touch surfaces, it also corresponds to a single, one-finger tap on
17 <h2>Right Clicking</h2>
19 The term <dfn>right-click</dfn> refers to the act of pressing and releasing
20 the rightmost mouse button (internally called <kbd class="mouse">Button2</kbd>,
21 but again your operating system may allow this to be reassigned).
22 This action is used to pop up <dfn>context menus</dfn> (hence the term
23 "context click", which you will also see). It is also used by default in
24 combination with the shift key to delete objects within the editor
28 Mac OS mice sometimes have only one button. On Mac OS if you press and hold
29 the Control key this is equivalent to right-clicking.
32 <h2>Middle Clicking</h2>
34 A <dfn>middle-click</dfn> refers to the act of pressing and releasing the
35 middle mouse button (<kbd class="mouse">Button3</kbd>, which may also be
36 reassigned). Not all all mice have a middle click button
37 (see the <a href="/setting-up-your-system/mouse/">Mouse</a> chapter for
38 details). Sometimes the scroll wheel acts as a clickable middle button.
39 This action is used for time-constrained region copying and mapping MIDI
43 <h2>Double Clicking</h2>
45 A <dfn>double click</dfn> refers to two rapid press/release cycles on the
46 leftmost mouse button. The time interval between the two actions that
47 determines whether this is seen as two clicks or one double click is
48 controlled by your system preferences, not by Ardour.
53 A <dfn>drag</dfn> primarily refers to the act of pressing the leftmost
54 mouse button, moving the mouse with the button held down, and then
55 releasing the button. On touch surfaces, this term also corresponds to
56 a single one-finger touch-move-release action.
59 Ardour also uses the middle mouse button for certain kinds of drags,
60 which will be referred to as <dfn>middle-drag</dfn>.
65 There are many actions in Ardour that can be carried out using a mouse
66 button in combination with a <dfn>modifier key</dfn>. When the manual
67 refers to <kbd class="mod1 mouse">Left</kbd>, it means that you should first
68 press the <kbd class="mod1"></kbd> key, carry out a left click
69 while <kbd class="mod1"></kbd> is held down, and then finally release the key.
72 Available modifiers depend on your platform:
74 <h3>Linux Modifiers</h3>
76 <li><kbd>Ctrl</kbd> (Control)</li>
77 <li><kbd>Shift</kbd></li>
78 <li><kbd>Alt</kbd></li>
79 <li><kbd>Mod2</kbd></li>
80 <li><kbd>Mod3</kbd></li>
81 <li><kbd>Mod4</kbd></li>
82 <li><kbd>Mod5</kbd></li>
85 The following section is almost certainly wrong. Will need to be checked
89 Mod2 typically corresponds to the <kbd>NumLock</kbd> key on many systems.
90 On most Linux systems, there are no keys that will function as modifiers
91 Mod3, Mod4 or Mod5 by default, but they can be setup using
92 <dfn>xmodmap(1)</dfn>. This can be rather useful.
95 <h3>OS X Modifiers</h3>
97 <li><kbd>Cmd</kbd> (Command, "windmill")</li>
98 <li><kbd>Ctrl</kbd> (Control)</li>
99 <li><kbd>Alt</kbd> (Option)</li>
100 <li><kbd>Shift</kbd></li>
103 <h2>Scroll Wheel</h2>
105 Ardour can make good use of a <dfn>scroll wheel</dfn> on your mouse, which can be
106 utilized for a variety of purposes. Scroll wheels generate vertical
107 scroll events, <kbd class="mouse">⇑</kbd> (ScrollUp) and
108 <kbd class="mouse">⇓</kbd> (ScrollDown). Some also emit horizontal
109 events, <kbd class="mouse">⇐</kbd> (ScrollLeft) and
110 <kbd class="mouse">⇒</kbd> (ScrollRight).
113 When appropriate, Ardour will differentiate between these two different
114 scroll axes. Otherwise it will interpret ScrollDown and ScrollLeft as
115 equivalent and similarly interpret ScrollUp and ScrollRight as equivalent.
118 Typically, scroll wheel input is used to adjust
119 <dfn>continuous controls</dfn> such as faders and knobs, or to scroll
120 vertically or horizontally inside a window.
