This still needs some improvements, after playing GraalOnline Era on a browser for a while now, I've realized that key presses are not always registered. Opening player profiles has also been an issue, as sometimes when you click onto players or yourself, it won't open their/your profile. Sometimes when you manage to open players profile or your own, it locks on that page, not being able to access More Actions, Back, or the Edit page.
WebGL has worked great, it just needs a bit more improving.
In addition to this post, it literally registers the Enter key as "Enter" in text boxes. E.g. I'm overhead chatting and then I press Enter to actually talk, but instead of talking I literally type the word "Enter".
