Keyboard's key repeat feature doesn't work in Audition

Question

For Audition CS6, I've reassigned zoom-in and -out to the keys "R" and "T" (like on Pro Tools).  It does zoom.  However, when holding down a key to zoom in or out (R or T), the key repeat function doesn't work.  I don't think the key repeat function works at al within Audition CS6.  Is this so?
My keyboard's keys DO repeat in all other programs though.  I like to zoom in quickly to either the playhead or to the IN or OUT of a selection.  Unfortunately, the end result is a mere one-zoom instance per one key click (down then up)  instead of what our PC/Mac's keyboard's key repeat function could do  (when using Pro Tools): allowing you to zoom in or out quickly by utilizing the computer system's keyboard key repeat function. As it is, I'm much slower having to "tap-tap-tap-tap-tap..." to zoom in and out.  Intolerable!
The mouse scroll wheel DOES zoom in/out smoothly though, oddly enough.

Answer 1

I just checked for the option to "zoom in on the play head," but couldn't
find anything.  I'm on the latest version of CS6 (5.0.2 build 7).  I see
"Synchronize selection, zoom level, and playhead *across files *in the
Waveform Editor."
I just tried checking and unchecking that, trying it on a single piece of
audio in the Waveform view.  But the scroll wheel zoom feature seems to
have a mind of its own.  I want to always be able to zoom directly to the
playhead*.  *That is, say I zoom out quickly via my scroll wheel.  Great.
That works fast and well.  I go to zoom back in to where the playhead is
moving (playing).  And say, then, my cursor a couple of inches before it in
the full zoomed-out view.  Mouse cursor is in the general area of the
playhead zoomed fully out as I am, but when I scroll back in, it zooms in
not to where the playhead is, but waaaay out in front.
