<title>JSwat - How to Add Shortcuts</title>
</head>

<h2>How to Add Shortcuts</h2>
<h3>Adding Shortcuts</h3>
<p>Adding keyboard shortcuts to JSwat actions is simple. Find out
what the name of the action is by looking at the action source
code. Say the action is the exit action, which amazingly enough, is
called 'exit'. To add a keyboard shortcut, or accelerator,
to this action we simply add a new default to the
<code>Defaults.java</code> file in the <code>jswat</code>
package.</p>
<p>The other part is a little more involved. The
<code>PreferencesAction</code> class must be updated to allow
customizing the new keyboard shortcut. I will leave this to the
astute developer to figure out (it is pretty obvious).</p>
<h3>Shortcut Values</h3>
<p>The allowable values for keyboard shortcuts are defined by the
<code>javax.swing.KeyStroke().getKeyStroke(String)</code> method.
That information is reprinted here for your convenience.</p>
<p>The keystroke string has the following syntax:</p>
<pre>
<modifiers>* (<typedID> | <pressedReleasedID>)
modifiers := shift | control | meta | alt | button1 | button2 | button3
typedID := typed <typedKey>
typedKey := string of length 1 giving Unicode character.
pressedReleasedID := (pressed | released)? key
key := KeyEvent keycode name, i.e. the name following "VK_".
</pre>
<p>If typed, pressed or released is not specified, pressed is
assumed. The button1, button2, and button3 modifiers refer to the
respective mouse buttons. Here are some examples:</p>
<pre>
"INSERT"
"control DELETE"
"alt shift X"
"alt shift released X"
"typed a"
</pre>
