Now that the code is in a better place:
- Click an inline's header (just the colored part) to select it with the keyboard selection cursor.
- Click again to deselect it.
- You can use "n" and "p" to jump to comments, so "click + n" is the same as the old "V" action.
- This also makes it easier to swap between keyboard and mouse workflows, since you can jump into things with the keyboard at any inline.
Also, make "Reply" render more consistently.
