> None of the web style solutions seem to be suitable for a keyboard based (tabbing style) grid to represent an itemized billing. I suggest you to build your own keyboard listener extension, frontend frameworks are don't really have built in support for this since it's too specific. You can very easily listen to all keyboard events with vanilla JS and trigger actions accordingly. Take a look at Angular 4, it has all the event handlers you need in the templates/view modules. https://coursetro.com/posts/code/59/Angular-4-Event-Binding https://coursetro.com/posts/code/59/Angular-4-Event-Binding Angular is more like a full feature framework with some enterprise feel to it. If you want a modular system with craftmanship level attention to detail (you can build your stack how you like it), then try React or Vue.js.
