Howard, I am using WindowEyes also, and use the right control 
button for the same reason you do.  I really didn't like the 
toggle on and off feature when using the space bar and I couldn't 
seem to mouse around and find the indicator that says you're 
transmitting or receiving.  At least I seem to remember something 
like that.  Jim WA6EKS.

More on echolink.
The settings of note are in tool s preferences.
On the first property sheet called "lists" are the show in index 
views, each
of these should be unchecked.
In the second property sheet dialog, there is a ptt control 
dialog, press
enter here and you can assign one of five keys as momentary push 
to talk
keys.
I use the left control, because window-eyes doesn't say anything 
when that
key is pressed.
I also choose momentary so the control acts like a mike button.
