In the hope I'm not teaching too many grandmothers how to suck eggs, I thought I'd add an explanation about the enhanced margin Bell feature. Essentially, when you are entering a braille document, you have the option to set a margin bell in the same way as you have on a Perkins Brailler. This is done via the Global menu, View Preferences dialog where you can set a position at which the bell will sound. To disable this, set it to zero. But in actual fact, it's not a bell, but a not very exciting beep which usually comes through the PC's internal speaker. However if you place a wave file called "margin.wav" into the Duxbury program folder - in the case of Beta 5, probably:- c:\Program Files\Duxbury\DBT 10.6 (Beta 5) it will play this instead. You can use almost any .wav file you like, and in the case of the attached, I found one on my system called "ding.wav", copied it to the above folder, and renamed it to "margin.wav". Now it sounds just like a Perkins. I'm sure many teachers will see the potential here when teaching 6 key entry of using different bell sounds for their students, if only to brighten up the lesson. George.
