New APIs for remappable keybindings #630
Description
Is your feature request related to a problem? Please describe.
Currently each chewing_handle_X API has predefined functionality, yet they are not documented. The behaviors are documented in the usage document only. So when IM want to disable Shift+Space for fullwidth toggle, or other behaviors, we have to provide specific options.
Describe the solution you'd like
Define public Chewing state machine states, and actions, and default key bindings. Then provide new set of APIs to configure the key bindings.
For example,
| State | Action | Default Key Binding |
|---|---|---|
| Entering | Input | Any |
| Entering | Toggle Fullwidth | Shift + Space |
| Selecting | Select 0 | 0 |
The selKeys option can be rebuild on top of this new feature.
Describe alternatives you've considered
Not at this moment.
