[news.eclipse.newcomer] Undo hotkey does not work for me.

[exquisitus <agz@xxxxxxxxx>]

Hello,

I'm trying to migrate to Eclipse 3.4.2 build M20090211-1700 from NetBeans.
Please help me to get rid of this anoyance: "Undo" does not work on Ctrl+Z when I'm editing my java 
code. It just shows Ctrl+Z below in the status line. I've bound another hotkey: Alt+Backspace to the 
undo command, but it does not work either. Undo works only when I click the "Undo" item on the main 
menu.

Please help!

Thanks,

Andrew
