On the previous version (<4.2) ios safari, the way to describe how to add a webapp to the home screen (used even by apple on http://www.apple.com/webapps/whatarewebapps.html was "tap the plus sign, and then tap “Add to Home screen."
Now there is no longer a plus sign.
Is there a proper name for the 'share button'? It's main feature is an arrow but there are two other buttons with arrows.
Any ideas (or the official name) for this button?
