That's really funny.

Some inconvenience:

 1. Tip is never change during one execution of 'perf report', even if
    I switch to another view using 'enter' and switch back. It should 
better
    if tips updated when redrawing.

 2. I think add a "Tip: " prefix to the content should be better, or 
users may
    confuse what he/her doing causes this message

 3. What about creating a tools/perf/Documentation/tips.txt and 
generate tips
    table dynamically?

Thank you.
