- * 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: 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
- * behavior.
- *
- * 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.
