I'm visually impaired and using screen reader software which reads text by 
Synthetic speech.  It was not easy for me to navigate a large table to find the 
first row of a particular wait event type.  With your proposal, I'll be able to 
move among tables with a single key press ("T" and "Shift + T".)  I'd also be 
happy about separating the section for wait events as you propose, because 
navigating in a long section is cumbersome.
