Ah I'm sorry I wasn't clear enough.
I have a textbox. I right clicked in the textbox and saw a default context menu pop up that had cut, copy, paste, undo etc. I wanted to add some things to it, so I made a new context menu and set the textbox to use that context menu. I added some stuff to it and when I right click in the textbox I see all the stuff in the context menu that I added, but now Cut, copy, paste etc are gone. I would just like to know how to add those back.
