In desktop applications like Explorer you can generally start to type element name (like folder or file) and it became focused. Web browsers implement similar behavior in drop down lists.

I need to do the same thing in GridPanel. User types 'a' and table focuses on first element with certain field starting with 'a'. Obvious solution is to add all letters to keymap but things start to get nasty if you have localization. Is there any simple way to implement this functionality?
