FAQ How do I provide a keyboard shortcut for my action?

Keyboard shortcuts are created by defining a key binding, using the org.eclipse.ui.commands extension point. When you define a key binding, you generally specify four things:

  • The ID of the configuration to which it applies.</li>
  • The context, or scope, for the key binding. For example, the text editor defines

a context that can override bindings from the global context.</li>

  • The ID of the command that you are creating a binding for. You can find

command IDs by browsing the plugin.xml file of the plug-in that defines that action.</li>

  • The accelerator sequence.</li>

You can also define a key binding that applies only to a particular locale or platform. For example, you can define an accelerator that applies only to a German Linux GTK installation of Eclipse. See the command extension point documentation for more details on these advanced features.

The following is an example key-binding definition. This binding sets the accelerator for the Java Sort Members action, which by default has no key binding:


The difference between a configuration and a context can be confusing at first. The configuration is explicitly set by the user; once it is set, it does not change. The context can be changed programmatically by any plug-in. For example, you can change the scope whenever your view or editor becomes active. Scopes can be queried and set by using the IKeyBindingService. This service can be accessed within a workbench part by using the method getKeyBindingService on IWorkbenchPartSite.
