thunderbird shortkey and other problem

[hyfanious]

Hi, installing Ubuntu 12.04 and using Thunderbird 11.0.1, I'm wondering how can I change shortcut key , like getting all new messages by pressing F9 instead of Shift+F5,
and also how can I see all my messages in a single folder named Inbox or somthing just like as what we see in Evolution, instead of accessing mails by each separated inboxs related to mail addresses.
tnx in advance.

one part is solved:
u can change shortcut keys by a add-on which u can find it here
first download it then use add-on in ur thunderbird then from option choose "Install Add-on from file" and add it, then use this add-on to change ur shortcut keys
but what about collection mails in one single Inbox folder?
