Apple tweaks Keynote software

Apple Computer on Wednesday released version 1.1 of its Keynote presentation software. The update adds several features and tackles some about the original. Changes have been made to the way that the program imports and exports PowerPoint files and to the way that the program handles QuickTime files. In addition, the company has reduced the size of files exported as PDF (portable document format) documents. Apple released the first version of Keynote at January's Macworld Conference & Expo in San Francisco.
