Hi Mike.  Glad you found it.  It is realy quite easy to use, once you get
familiar with it.  When you are connected to a station, you can use the
space bar or the enter key to go into transmit and pressing it again
togals back to recieve.  The only tricky thing is if you are in the list
and someone connects to you, you have to close that window before you can
transmit. When you are transmitting, you will see a countdown timer in
the title bar.  That is one way to know for sure that you are
transmitting.  With window-eyes, I have labeled the graphics at the
bottom of the screen that change from recieve to transmit.  You can also
click on this graphic to togal between transmit and recieve, but I find
the space bar is easier.

Hope this helps:
