thanks for your mail / posting.

(I skip the reply to your previous contact form mail on the same 
topic and just put you in the Bcc of the reply mail I send to the forum)

The problem is quickly located: PowerPoint X - as opposed to 
PowerPoint 2004 - has no AppleScript support and thus does not work 
with the Behaviour for PowerPoint, which makes use of PowerPoint's 
AppleScript-support to allow you to start/stop and navigate 
PowerPoint presentations.

There is a (partial) solution, though.

1) Since PowerPoint X does not offer any keyboard shortcut (at least 
I don't know any) that would start the presentation, use the touchpad 
of your MacBook or virtual mouse of Remote Buddy to start the 
presentation from the menu.

2) Use your remote to enter the menu and activate the "Virtual Cursor 
Keys" behaviour from the "Input devices" menu. This will send left 
and right cursor keys to the frontmost app (PowerPoint when running a 
presentation) and will thus make it skip forward and backward through 
your slides.

If anybody knows a key combination in PowerPoint v.X that would start 
a presentation, I could make the behaviour directly support 
PowerPoint v.X without this two step procedure ..

Best regards, 
Felix
