They are hinted at if you mouseover the various icons in the composer, but you probably never did that either. 🙂

There’s also a [composer help button](https://meta.discourse.org/t/composer-help-button/22748) plugin that’ll give you a list of them.

Could be. On this Mac, `command-z` undoes the typing that I did, but not the bold. I think that undo is also similarly broken under Linux, but I’ve never thought to call it a bug.
