16  * FlKeyEmbedderCheckedKey:

18  * The information for a key that #FlKeyEmbedderResponder should keep state
19  * synchronous on. For every record of #FlKeyEmbedderCheckedKey, the responder
20  * will check the #GdkEvent::state and the internal state, and synchronize
21  * events if they don't match.
22  *
23  * #FlKeyEmbedderCheckedKey can synchronize pressing states (such as
24  * whether ControlLeft is pressed) or lock states (such as whether CapsLock
25  * is enabled).
26  *
27  * #FlKeyEmbedderCheckedKey has a "primary key". For pressing states, the
28  * primary key is the left of the modifiers. For lock states, the primary
29  * key is the key.
30  *
31  * #FlKeyEmbedderCheckedKey may also have a "secondary key". It is only
32  * available to pressing states, which is the right of the modifiers.
