Eclipse 4.2 seem has some built-in shortcuts, such as Ctrl+P, Alt+C, Alt+X etc, you can not find them from “Window->preferences->General->Keys”. I’d like to re-define these shortcuts, e.g. bind Alt+X to run maven build, but when i press Alt+X, at the bottom right corner of Eclipse, it flashes quickly and my mouse is out of control, i think this is because of shortcut conflict.
Anyone who know how to disable the built-in shortcuts? Thanks.
Edit:
Ctrl+p is only bind to one action.

When i click Ctrl+p, the bottom right corner show, this message is from from eclipse:

Well, the above is the good situation–at least you can choose which action to run. for Alt+P, Alt+c you have no chance to choose, eclipse is flipping and you are out of control.
I found the root cause of this problem, i import all my keys from Eclipse 3.7 to 4.2, most of them works, however some of them conflict but Eclipse fails to show the conflict shortcuts, Let’s say, Ctrl+P, this is print shortcut for eclipse by default, in eclipse 3.7 i bind Ctrl+p to another command, after import, eclipse 4.2 shows just like 3.7(see above), however in fact it still has conflict even though it does not show the conflict. I think this might be an eclipse bug. I’m the one who use shortcut extensively. Hope this help others with migrating shortcuts.
