Key bindings
The association between a command and the key combinations that should
invoke the command is called a key binding. Plug-ins can define key
bindings along with commands in the
org.eclipse.ui.bindings
extension point.
...
<key
sequence="Ctrl+S"
commandId="org.eclipse.ui.file.save"
schemeId="org.eclipse.ui.defaultAcceleratorConfiguration">
</key>
...
There is our friend org.eclipse.ui.file.save. Recall our
hypothetical action definition:
<extension point = "org.eclipse.ui.actionSets">
<actionSet id="com.example.actions.actionSet"
label="Example Actions"
visible="true">
<action id="com.example.actions.action1"
menubarPath="additions"
label="Example Save Action"
class="org.example.actions.ExampleActionDelegate"
definitionId="org.eclipse.ui.file.save">
</action>
...
</actionSet>
</extension>
The sequence attribute for a key binding defines the key
combination that is used to invoke a command. So, it follows that when our example action set is active, our save action will be invoked
when the user chooses Ctrl+S.
Likewise, when the
workbench SaveAction is active, the same key combination will invoke it
instead, since the workbench uses the same command id for its SaveAction.
To complete the example, we need to understand what the configuration
is all about.
