a question clout orca and one about the keyboard

[camminando fastwebnet it]

I installed the last version on synaptic of gnome-orca and festival-freebsoft-utils, festvox-itapc16k and festlex-ifd and if I in on the text of a mail of evolution it doesn't say the row, also on firefox it doesn't say the rows. How could I do?
And them I wonder if there is possibility to slow the key repetition, I already went on system->preferences->keyboard and I put the slowest velocity but it's still very fast
