Modify Hotkey for Age of Empires 2

I will probably purchase the remastered edition of Age of Empires 2 when it launches on April 9th on Steam, but at this time I do not have my original copy of the game so I cannot test this feature...

Question: Is it possible to assign your own hotkeys for Age of Empires 2 (and expansions)? If not, what is the buzz word for keypads/boards that are tailored for RTS hotkey access (not asking for recommendation, just the industry standard)?

Thanks in advance.
