Underlining + formatting

Not sure if this is a bug, as before WYSIWYG we don’t support underline, nor do most other Markdown sites. Being able to use Ctrl+U to underline is something we should’ve blocked, because the result is misleading. It looks like the effect is applied, but that’s the browser doing its work.

We only store Markdown plain text in our server, and the syntax does not support underlining right now. In other words, after refreshing, no underline formatting would work. All effects are temporarily made by the browser.

So I’m not sure how to deal with this before WYSIWYG. Block Ctrl+U so the temporary underline effect doesn’t work?
