Is there a way to do this without overriding the standard contextual menus? This can be filed as so obscure as not needing a reply, but I have been thinking about a method for enabling validations for fields in edit mode using a right click or something. I could hack it by selecting the field and then running something in the message box, but wouldn't that be a cool plugin?

I have a concat validation that will concatenate a list of fields and put it in another field, I have a noupdate validation that deletes the key in an array before updating the database, so that something like a password can only be created when creating a new record, and requires another handler to change it.
