Code snippets for custom keyboard shortcuts

Firefox already have very large number of keyboard shortcuts, and other addons also provide their own keyboard shortcuts, I cannot find out safe combinations for my features. So I gave up and decided to provide only APIs for other addons. Please use generic addons to customize keyboard shortcuts which can define custom actions based on scripts. Sorry.
