Several new options in the action routines.
"scrollbar" to move the display and not the cursor.
"nobell" to allow silent operation, this one should be popular ;-)
"stutter" and "column" options for next_page & previous_page
"tail" option in forward_word
scroll_right & scroll_left work similar to their scroll_up scroll_down counterparts.
All of these allow emulation of Mac development environments.
