Script Summary: Use Ctrl+Shift in Firefox to switch between RTL and LTR modes in gmail
Since I've found no way to detect specific right/left ctrl/shift in javascript, this script only toggles between rtl and ltr each time a ctrl+shift combination is pressed.
If you can think of a good way to improve this, please comment.
Update: (December 17th, 2011) Now supports gmail's new look.
Update: (July 15th, 2009) Changed event for better performance on Firefox on Linux.
