My daughter tells me and her sister she suffers from ADOS, (Attention
Deficit Oh Shiny)
or as I call it Golden Retriever Syndrome, as shown in the movie "UP" by
Doug.

Sorry but I couldn't help myself, and I too keep finding things I didn't
know about, and I
don't know how to help other than to suggest trying Google to find a web
site that may have
a list of Ubuntu Hot Keys, maybe google that term or something like it.
