+### Customizing Keydown Behaviour
+---
+
+## selectOnKeyCodes <Badge text="v3.3.0+" />
+
+`selectOnKeyCodes {Array}` is an array of keyCodes that will trigger a typeAheadSelect. Any keyCodes
+ in this array will prevent the default event action and trigger a typeahead select. By default, 
+ it's just `[13]` for return. For example, maybe you want to tag on a comma keystroke:
+ 
+<TagOnComma /> 
+ 
+<<< @/.vuepress/components/TagOnComma.vue
+
+## mapKeyDown <Badge text="v3.3.0+" />
+
+Vue Select provides the `map-keydown` Function prop to allow for customizing the components response to 
+keydown events while the search input has focus.
+
+```js
+/**
+ * @param map {Object} Mapped keyCode to handlers { <keyCode>:<callback> }
+ * @param vm {VueSelect}
+ * @return {Object}
+ */
+(map, vm) => map,
+```
+
+By default, the prop is a no–op returning the same object `map` object it receives. This object
+maps keyCodes to handlers: `{ <keyCode>: <callback> }`. Modifying this object can override default
+functionality, or add handlers for different keys that the component doesn't normally listen for.
+
+Note that any keyCodes you've added to `selectOnKeyCodes` will be passed to `map-keydown` as well,
+so `map-keydown` will always take precedence.
+
+**Default Handlers**
+
+```js
+//  delete
+8: e => this.maybeDeleteValue()
+
+//  tab
+9: e => this.onTab()
+
+//  enter
+13: e => {
+    e.preventDefault();
+    return this.typeAheadSelect();
+}
+
+//  esc
+27: e => this.onEscape()
+
+//  up
+38: e => {
+    e.preventDefault();
+    return this.typeAheadUp();
+}
+
+//  down
+40: e => {
+    e.preventDefault();
+    return this.typeAheadDown();
+}
+```
+
+### Example: Autocomplete Email Addresses
+
+This is example listens for the `@` key, and autocompletes an email address with `@gmail.com`.
