I tried to install acroread using both the synaptic package manager and
the command line method you recommended In both cases, the system said
package not found Do I need to add a software source to get this
package???? If yes, which one? If not, what now?

BTW thanks for the quick response. Much appreciated.

Using Adobe Reader 8 choose Edit => Preferences => Accessibility

To install it use Synaptic and search for Adobe or at the command line
sudo apt-get install acroread.
