16 * FlKeyEmbedderCheckedKey:
17 *
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.
