Trap EVERY MenuEvents ?

In a running project, I sometimes go elsehere (the OS seems to react to a “phantom” MenuEvent Keyboard Shortcut.

is it possible to trap somewhere every Keyboard shortcut / Menu Event and set action only for those I want to ?
Sorry, this looks strange, but when I press the right arrow key (only) in a text field (internet web page) and I had a page change instead of a-single-move-to-the-right–by-one-character…

Idea(s) ?
