Notebooks for iPhone Answers

I'm having trouble following the instructions (below) to add a new task to Inbox from a text selection. I have a book named Inbox at the top level. When I'm in a normal note (not a task list), I select a line of text which I want to add to the Inbox as a task, but the action icon is not available as the lower half of the screen is taken up by the onscreen keyboard. If I press the lower right keyboard button to hide the keyboard and show the menu bar which includes the action icon, the text is unselected so I can't add it as a task. Am I doing something wrong here?

Instructions: "If you have a book/task list named "Inbox" at the top level of Notebooks, you can now add text selections as new documents/tasks to that book through the action "New Task in Inbox"."
