Vue supports key modifiers on v-on for handling keyboard events. Let's take an example of keyup event with enter keycode.
<!-- only call `vm.show()` when the `keyCode` is 13 -->
<input v-on:keyup.13="show">
Remembering all the key codes is really difficult. It supports the full list of key codes aliases
* .enter
* .tab
* .delete (captures both “Delete” and “Backspace” keys)
* .esc
* .space
* .up
* .down
* .left
* .right
Now the above keyup code snippet can be written with aliases as follows,
<input v-on:keyup.enter="submit" />
<!-- OR with shorthand notation -->
<input @keyup.enter="submit" />
