[RWP] how to do audio quantizing with reaper?

Maybe you could Google Stretch Marks, which will let you move all the 
transcients; loud places; in the track to the nearest stretch marker in 
a single action.
You could make an audio track with clicks on it; like place a single 
kick drum beat at the beginning of measure 1, beat 1, then stretch it as 
an item so it would repeat at every beat.
You'd need to create such a click track exactly as long as your present 
drum track.
Then somehow the Stretch Marks method will force your audio drum track 
to fit the time on the click track.
Stretch Marks is in the Reaper 4.4402 items menu, with a submenu to 
place stretch marks, but I haven't found anything on how to use it.
It's brand new, so the sighted users in the forums were just guessing, 
same as us, on how to use it; when I looked, several weeks ago, but 
there eventually should be more info on using it.
When I google, I always start the search terms with cockos..reaper..
then a very few words, like Stretch marks.
If I don't include cockos I get hits on something called Don't Fear The 
Grim Reaper, songs from a group named Grim Reaper, and piles of other 
non related stuff.

Later today I'll go try my luck to learn more about Stretch Marks.
I really really want to do naughty things with it; like force the words 
of a speech from some very pompous dignified official to the beat of a 
really hip breakBeat.  smile.
There's an app for the iPad that already does this; a real side splitter!
