I tried to do my best:

I guess the "Key Repeat" setting is the relevant here, and I've tried my 
best.

I recall that there is some app out there that allows me to select 
faster than fast.  But I don't have that.  And actually, what I've got 
now is just about right.  Maybe I could go a _little_ faster, but not 
much.

Hm.  I've just tried again with <Cursor-Up>, and it seems it doesn't 
render every email, only about every 5th or every 10th.  But still, it 
doesn't move as fast as it could.  (And why does it render any email 
while I'm still holding down the key?)

I don't know how it works for others, but if others experience the same 
problem, may I suggest to set the render delay to the keyboard repeat 
interval plus epsilon?
