This is one of my biggest peeves. In iOS 6 there was an edit button. When you pressed it the Delete and Forward buttons became active.
But now with iOS 7 we're all so clever that we don't need any indication at all. So poke, swipe, and hold. One or none of those may work.
So remember, tap and hold:
- Unless the message is just an HTTP link, then you cannot do anything except Open / Add to Reading List / Copy.
- Unless the message is just an address, then you cannot do anything except Open in Maps / Add to Contacts / Copy.
- If the message has some text besides an HTTP link or address, then you need to try and tap and hold that text. And if you instead accidently (or intentionally) tap and hold the link or address and choose copy, the non-link portion of the message isn't copied so you can't paste a name and address somewhere else.
Did I miss anything?
