You can copy and paste formatted text from rich text documents (e.g. Microsoft Word .doc), though sometimes there will be small changes to the formatting when pasting due to limitations of the rich text format.
You will not be able to paste stand-alone images or PowerPoint slides into the Text or Reference Panes – you should use the Image Pane for this.
You can paste both web page URLs and links to files on your PC. For files, drag the file in Finder into either pane in Audio Notetaker to get a URL-style link. The file needs to be dropped onto the text cursor's position.
When you click on the link, Audio Notetaker will bring up the web page or file - as long as you haven't moved it in the meantime.
