Hi.  Thanks for trying.  Let me try to explain my need more clearly.

I have a split frame.  Left window is code, right window is results of 
the compile command.  I get a bunch of warnings and/or errors.   I do a 
few (next-error) commands.  If I switch windows into *compile* window and 
turn on hl-line-mode, it highlights the line where the cursor is at.

Now I do next-error again.  In my emacs (maybe it's theme related?) I see 
a little triangle in the left fringe of the *compile* window.   The 
little triangle at the edge of the window moves to the next error, and my 
cursor jumps to the next error, but the highlighted region of the 
*compile* window is still the line that was highlighted when my cursor 
was over there.  If I swap windows the highlighted region then updates to 
show the current error, but I'd like that to happen without switching 
windows all the time.

What I want is a quick way to track what the current error being pointed 
to in the *compile* window is.  hl-line-mode would be awesome, but making 
that triangle indicator bigger or bolder or more colorful would work 
too.  The problem is it takes my eyes too long to track what the current 
error message associated with point is.

Any ideas?
