Are Their Any Other Graphical Screen-Readers in Linux, Other than ORCA?

[Linux for blind general discussion]

Well, thanks for your comments. ORCA doesn't seem very intuitive, actually its 
the navigation which seems a large challenge. 1 of my other sighted Linux 
experts were here last Sunday, trying to hunt his way around ORCA, found it as 
challenging as I have. Sure in any graphical, tabbing around web-sites would be 
an obvious choice, but the lack of an up-and-down menu the way midnight 
commander, alpine, or lynx in console, or as I said earlier, a win95/98 desktop 
experience wasn't too bad. Thanks again
