I write with the aid of a dictaphone, so was delighted to discover Word 2004's new audio-recording feature. I was then disappointed to find that it lacks keyboard shortcuts for play, stop, pause, etc. Reaching for a mouse is not much better than reaching for a dictaphone. Also, the NoteBook module does not offer the option of creating macros.
However, you can still automate these actions and asign them keyboard shortcuts using Visual Basic. Just create a new macro. Choose "Macros..." from the Macro sub-menu of the Tools menu. Type a new name and hit the Create button. Then place the following line directly above the "End Sub" statement:
WordBasic.AudioNotesPlayReplace Play with Pause, Stop, etc. as required. Quit out of the Macro editing environment and assign a keystroke in the usual way.
