I am thinking this is a page that needs to be updated...

About 3/4 of the way down under the section aligning to the timeline there is a point about using CTRL+W to zoom to normal on the timeline zoom, in 7 this actually closes the project. Also, CTRL+ [ with CTRL + ] do not zoom in and out as indicated. It appears the only way to zoom now is with the slidebar.
Since this isn't really a bug I am hoping someone from the team sees this or it can be bumped up to them.
