How to switch between tab using shortcut key in RCP application

问题


In my RCP application, there are multiple ViewParts and EditorParts open. I want to define a shortcut key to switching between these parts.

Is there a way to implement this?

Custom KeyBinding sequence example : CTRL + TAB to switch between visilble Modules or Editors Forward direction using Eclipse RCP.

you press CTRL + TAB second time to open another editor and close previous editor using RCP Eclipse.
