Keyboard Savior Xtreme av Joe Ulfers

Stops keyboard shortcut hijacking by blocking sites from seeing keyboard events. Makes exceptions when focus is in certain editable areas that often require keyboard handlers for good behavior. These include:

• Textual inputs
• Rich-text editors
• Media with custom controls

Allows whitelisting a site — allowing it to see all keyboard events — either by clicking the toolbar icon or editing add-on preferences.
