Pages won't let me type
I have been working on this document for several days and in the middle of highlighting and moving a section of text, that portion of text disappeared and blue frame appeared around the text on that page. I am no unable to undo that action, type in any portion of the document and have absolutely no idea how remove the blue frame and continue my work.
Please help. This document needs to be sent out ASAP.
MacBook Air, OS X Yosemite (10.10.2)
