public class BrowserAction

extends org.eclipse.jface.action.Action

Text actions (cut, copy, paste) for the Web browser. This code had to be copied from org.eclipse.ui.internal.browser because access to it from other bundles is restricted.

This code is borrowed from the internal browser code (org.eclipse.ui.internal.browser) by John Bradley. It needed to be duplicated because the code was internal and not available for reuse outside in its original form.
