Shortcut.js

A Javascript library that lets you trigger events using keyboard shortcuts.

This library is a ES6+ version of Rick’s Shortcuts, I updated it to be used with ES Modules and newer patterns.

Installing

Download the shortcut file using via wget:

wget https://raw.githubusercontent.com/VitorGouveia/Shortcut.js/master/shortcuts.js

then, just import it into your file:

import { shortcut } from "./shortcuts.js";

Usage

Adding Shortcuts

To bind a keyboard shortcut use the add function:

shortcut.add('ctrl+shift+m', () => {
    // your code here
})

Bnding to a custom element

To bind a keyboard shortcut to a custom HTML element use the add function with a third parameter:

const element = document.querySelector("#container")

shortcut.add('ctrl+shift+m', () => {
    // your code here
}, element)

Removing Shortcuts

To un-bind/remove a keyboard shortcut use the remove function:

shortcut.remove('ctrl+shift+m')

Modifier Keys

The following modifier keys are supported:

cmd (Mac only)
ctrl
alt
shift

Examples

see the example for more usage details.
