Keyboard shortcuts not working as expected in the Python Shell Buffer

Typical keyboard behavior unsupported within the Python Shell Buffer (bottom left pane in Rodeo UI).

Steps

• launch rodeo
• place cursor in the lower right pane AKA python shell buffer
• type some words
• execute one of the below keyboard shortcuts to see irregular cursor and selection behavior

expected

• command+delete on OS X => should delete all text to the BOL
• control+u on OS X => should delete all text to the BOL
• control+k on OS X => should delete all text to the EOL
• command+shift+left => should select all text from cursor to the BOL
• command+shift+right => should select all text from the cursor to the EOL
• option+delete => should delete all text to the BOL

e.g. if you hit option+delete i expect this to delete all text that i have typed behind my cursor "impro" should be deleted...

actual

• not only do some shortcuts not work, but it's worse than that. some shortcuts actually do something that is NOT expected
• e.g. command+shift+right and command+shift+left simply move your cursor to the EOL and BOL respectively without selecting any text at all. this is very unusual behavior.
