Within eclipse you can use the IFocusService to register a specific
control to the system (using an id, usually).

Then you can activate a handler for that Control using the appropriate
activeWhen clause (and org.eclipse.ui.handlers) or by using a Expression
and IHandlerService#activateHandler(*).

See ISources and http://wiki.eclipse.org/Command_Core_Expressions for a
discussion of variables available, and IFocusService javadoc for a
description of its use.
