I recently blogged about how web apps have hotkeys too. To encourage more developers to add hotkeys to their web applications, I created a jQuery plugin called jQuery.hotKeyMap.js and a sample application.
I just added a download link for the source code:
It’s an static web app but needs to be served in a server (e.g. python3 -m http.server 8765). Hope you find it useful!
