Where do I find a proper instruction manual for Windows Live Mail?  I'm using version 2012, but I think it's pretty much the same as WLM 2011.  When I click the help button it takes me to here: http://windows.microsoft.com/en-gb/windows-live/windows-essentials-help?t1=t6#v1h=tab4.  This is not a full help page, it just answers random questions.

In particular I want to know keyboard shortcuts for WLM.

Thanks.
