* Supported keybindings:

* Refer to defaultExCommandMap below.

*
|
|
* Registers: unnamed, -, a-z, A-Z, 0-9
|
|
* (Does not respect the special case for number registers when delete

|
* TODO: Implement the remaining registers.
|

*
|
|
* Marks: a-z, A-Z, and 0-9

|
|
*
|
|
* Events:

|
|
* 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
|
|

|
|
* 5. Key handler (the main command dispatcher) implementation
|
