| <h3>Contexts and key bindings</h3> |
| |
| <p>A <b> context</b> can be specified for a key binding so that the binding is only available when the user is |
| working within a specific context. Contexts are declared in the |
| <b><a href="../reference/extension-points/org_eclipse_ui_contexts.html">org.eclipse.ui.contexts</a></b> |
| extension point.</p> |
| |
| <p>A context can be bound to a key binding by specifying the id of the context when the key binding is defined. |
| For example, if we only wanted the save command to work while the user is editing text, we could specify |
| a context for the key binding: |
| </p> |
| <pre><extension |
| point="org.eclipse.ui.bindings"> |
| <key |
| sequence="Ctrl+S" |
| commandId="org.eclipse.ui.file.save" |
| <b>contextId="org.eclipse.ui.textEditorScope"</b> |
| schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"> |
| </key> |
| </extension> |
| ... |
| </pre> |
| (See <a href="workbench_advext_contexts.htm">Contexts</a>) for a more detailed discussion |
| of contexts and how they are defined. |
