[Hammer Attila <hammera pickup hu>]

Dear List!

I tryed select lines any webpage with Firefox3 and Orca, but the 
selection is not happened.
Pressed shift+up arrow, shift+down arrow, not worked this usual keyboard 
command.
ctrl+shift+left or right arrow work correctly.
Have anybody confirm or test this problem? I using Orca 2.22.2 version.

Thanks,

Attila
