“How Can I Clip — The Services Menu Items are Dimmed or Do Nothing?”
 
Not all applications properly support the OS X Services menu.  If you ever make a selection and find the clipping service items are dimmed, try clipping using the contextual menus.  If the application does not support contextual menu plug-ins, you can clip using NoteBook’s Dock icon: copy the selection to the Clipboard, then Control- or right-click NoteBook’s Dock icon and choose a Clipping Service from the Paste to menu.
