In the previous version of pages, 09 and 4.3, the first letter of any new paragraph would automatically capatalize as would each succeding first letter of a next sentence. The pronoun "I" would automatically capatalize also.
I found I couldn't get these features to work and called Apple Tech support and apparently these features are not in the new pages 5.0 which set itself as the default program.
How can I revert to Pages 4.3 as default ?
I have also downloaded OX 10 Mavericks
The Mac App Store kept Pages 4.3 in the Applications folder when you upgraded to Pages 5.
First, if you opened documents with Pages 5, open them with Pages 5 again and go to File menu (on the menu bar) > Export > Pages '09. By doing this, you will be able to open them with Pages 4.3.
Then, open a Finder window, choose Applications in the sidebar and open Pages 4.3 from there. To access to it quickly, you can drag its icon to the Dock.
Apple has announced that iWork for Mac will recover some features in the upcoming months. Read > http://support.apple.com/kb/HT6049?viewlocale=en_US&locale=en_US
