Alt+1 and other Alt-modified number keys in XenForo

[Cath O'Deray]

For reference (I thought this was discussed years ago, I can't find the topic):

This XenForo behaviour can be a problem if, for example, a FreeBSD Forums topic is at the first tab in a window.

… Alt+1 - Alt+8 opens the corresponding tab … Alt+9 opens the last one.

Alt+1 will navigate away from the topic, to:

New posts

forums.freebsd.org

… and so on. Don't key Alt-4 if this topic is the fourth tab, don't key Alt-5 if it's the fifth tab …
