+ * Supported keybindings:
+ *
+ * Motion:
+ * h, j, k, l
+ * gj, gk
+ * e, E, w, W, b, B, ge, gE
+ * f<character>, F<character>, t<character>, T<character>
+ * $, ^, 0, -, +, _
+ * gg, G
+ * %
+ * '<character>, `<character>
+ *
+ * Operator:
+ * d, y, c
+ * dd, yy, cc
+ * g~, g~g~
+ * >, <, >>, <<
+ *
+ * Operator-Motion:
+ * x, X, D, Y, C, ~
+ *
+ * Action:
+ * a, i, s, A, I, S, o, O
+ * 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: 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 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.
