for keyboard selection of the output text, e.g. Arrow Keys
to move the cursor, Shift + Arrow Keys to create a text
selection, and '^C' to copy the selected text to the paste buffer.
The caret cursor can be disabled by disabling the widget's
"visible focus" using clear_visible_focus(), inherited from the
Fl_Widget base class. Doing this also disables the widget's
keyboard navigation.
