Keyboard Accessibility Options

[sicsol]

It would be great to give the ability to turn off specific keyboard events from the accessibility/feature list of the components.

As an example not to allow SPACE to select an item in Listbox for example in our particular case we would like to implement our own search functionality however every-time we use the spacebar inside the input it closes the menu and selects an item.
