15 * FlKeyEmbedderCheckedKey:
16 *
17 * The information for a key that #FlKeyEmbedderResponder should keep state
18 * synchronous on. For every record of #FlKeyEmbedderCheckedKey, the responder
19 * will check the #GdkEvent::state and the internal state, and synchronize
20 * events if they don't match.
21 *
22 * #FlKeyEmbedderCheckedKey can synchronize pressing states (such as
23 * whether ControlLeft is pressed) or lock states (such as whether CapsLock
24 * is enabled).
25 *
26 * #FlKeyEmbedderCheckedKey has a "primary key". For pressing states, the
27 * primary key is the left of the modifiers. For lock states, the primary
28 * key is the key.
29 *
30 * #FlKeyEmbedderCheckedKey may also have a "secondary key". It is only
31 * available to pressing states, which is the right of the modifiers.
