Being left handed I walways used the home and end keys to fly and land. Now they don't work for that, in fact, they don't work for ANYTHING!
If you are not going to use the two keys for a different purpose, why take away the current functionality and leave then useless?
EDIT: I see what you have done, with the chat bar open the Home and End keys work as word processing keys.....still don't like it.....guess I will have to get used to it
