/**
* Supported keybindings:
* Too many to list. Refer to defaultKeyMap below.
*
* Supported Ex commands:
* Refer to defaultExCommandMap below.
*
* Registers: unnamed, -, a-z, A-Z, 0-9
* (Does not respect the special case for number registers when delete
* operator is made with these commands: %, (, ), , /, ?, n, N, {, } )
* TODO: Implement the remaining registers.
*
* Marks: a-z, A-Z, and 0-9
* TODO: Implement the remaining special marks. They have more complex
* behavior.
*
* Events:
* 'vim-mode-change' - raised on the editor anytime the current mode changes,
* Event object: {mode: "visual", subMode: "linewise"}
*
* Code structure:
* 1. Default keymap
* 2. Variable declarations and short basic helpers
* 3. Instance (External API) implementation
* 4. Internal state tracking objects (input state, counter) implementation
* and instantiation
* 5. Key handler (the main command dispatcher) implementation
* 6. Motion, operator, and action implementations
* 7. Helper functions for the key handler, motions, operators, and actions
* 8. Set up Vim to work as a keymap for CodeMirror.
* 9. Ex command implementations.
