Bug 168757 [KeyBindings] Add keybinding for 'collapse all' button in Navigator & Package Explorer
Just a nice to have - would be very handy to assign something like CTRL-minus to the 'collapse all' button in Navigator and Package Explorer views (really, anything w/ a tree view and than button).

		filterGroup.fillActionBars(theActionBars);
		if (collapseAllAction != null) {
			theActionBars.getToolBarManager().add(collapseAllAction);
		}
		if (toggleLinkingAction != null) {
			menu
					.insertAfter(IWorkbenchActionConstants.MB_ADDITIONS

			theActionBars.getToolBarManager().add(toggleLinkingAction);
