+ * f<character>, F<character>, t<character>, T<character>
+ * $, ^, 0, -, +, _

+ * %
+ * '<character>, `<character>
+ *
+ * Operator:
+ * d, y, c

+ *
+ * Operator-Motion:

+ * Action:

+ * zz, z., z<CR>, zt, zb, z-
+ * J
+ * u, Ctrl-r
+ * m<character>
+ * r<character>
+ *
+ * Modes:
+ * ESC - leave insert mode, visual mode, and clear input state.
+ * Ctrl-[, Ctrl-c - same as ESC.
+ *
+ * Registers: unamed, -, 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

+ *
+ * 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 instanstiation
+ * 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.
