How to collapse all LOGBOOKS at once?

[William Denton]

The only thing I really use drawers for is with clock tracking, so for me this 
is just about :LOGBOOK: but it could be about other types of drawers, or all 
drawers:  is there a way to collapse them all at once?

When I'm fixing up the amounts of time I've been working on this, or when I sync 
a file across two machines, I often end up with a lot of LOGBOOK drawers open 
but they're just taking up screen space.  Using TAB to close them one by one is 
good for a bit of tidying, but I'd like to do them all at once.

Thanks,

Bill
