Alt-Arrow Key Up Does Not Input Last Message

[KevinTyrrell]

Expected: Pressing alt + Arrow Key Up with the BigInputBox showing should display the last sent message, as the normal chat box does.
Actual: Pressing any key combination has no effect on repeating the last message.

e.g. with the default chat UI, if you wanted to write Hello 3 times, you would do:
Enter -> Hello -> Enter
Alt + Arrow Key Up -> Enter
Alt + Arrow Key Up -> Enter

This feature should be emulated if possible

Works fine for me. Alt+Up and Alt+Down cycle through chat history. No idea why it doesn't for you. Are you on retail or one of the classics?
