Wiki home page - Minor formatting suggestions.

[GrantRobertson]

On the wiki home page, the row with "Ctrl-F7New Group" seems to have a typo in the Markdown. I'm guessing that "New Group" should be in the second column.

The cell that says "n/p/up/down" could probably be rearranged to say, "n/p/down/up" for consistency, since "n" corresponds to "down" and "p" corresponds to "up."

Like I said, minor suggestions.

Sorry, I couldn't clone the wiki and make a pull request because I don't know how to use git yet. But, I figured any help is better than none. I also can't see any way to add the "documentation" label to this issue. I'm assuming that that can only be added by someone with authority in the project.
