[jquery] multiple key press handler

related sololearn Q&A

This is just a basic example of how handle multiple keys press with JQuery : watched keys sequence is [a]+[b], also taking account of [shift] keys

As we are listening for keys events for whole document, in code playground web context, we need to set focus to the inner document (the iframe holding your playground output, to avoid the need of user touch/click the iframe... (see 'onload' attribute in Html source)

[edit]
doesn't work in app' context: touch/click screen before hit keys ;)

[edit2]
Fixed, now works in both playground contexts...

Below in document will be logged the watched sequence, all keys will be logged in console...

[edit3]
update with little mistake fixes (two ways) in handling of keys state object ^^
