+/// Create a keymap plugin for the given set of bindings.
+///
+/// Bindings should map key names to [command](#commands)-style
+/// functions, which will be called with `(EditorState, dispatch,
+/// EditorView)` arguments, and should return true when they've handled
+/// the key. Note that the view argument isn't part of the command
+/// protocol, but can be used as an escape hatch if a binding needs to
+/// directly interact with the UI.
+///
+/// Key names may be strings like `"Shift-Ctrl-Enter"`—a key
+/// identifier prefixed with zero or more modifiers. Key identifiers
+/// are based on the strings that can appear in
+/// [`KeyEvent.key`](https:///developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key).
+/// Use lowercase letters to refer to letter keys (or uppercase letters
+/// if you want shift to be held). You may use `"Space"` as an alias
+/// for the `" "` name.
+///
+/// Modifiers can be given in any order. `Shift-` (or `s-`), `Alt-` (or
+/// `a-`), `Ctrl-` (or `c-` or `Control-`) and `Cmd-` (or `m-` or
+/// `Meta-`) are recognized. For characters that are created by holding
+/// shift, the `Shift-` prefix is implied, and should not be added
+/// explicitly.
+///
+/// You can use `Mod-` as a shorthand for `Cmd-` on Mac and `Ctrl-` on
+/// other platforms.
+///
+/// You can add multiple keymap plugins to an editor. The order in
+/// which they appear determines their precedence (the ones early in
+/// the array get to dispatch first).
