How to Rename a List

Lists can be renamed by first tapping the “Edit” button:

This puts the list into “edit mode”.  Note how the background of the list’s name changed to white.

Tap on the name of the list to make the keyboard to appear. 

Tapping on the keyboard’s “Done” button (lower right) will dismiss the keyboard while keeping the list in edit mode.

Tapping the navigation bar’s “Done” button (upper left) will both dismiss the keyboard and exit the list out of edit mode.
