source ktAutoSnappablePlayBackSlider.mel

to toggle ON/OFF

name is exactly what it is doing

its for animation... for time slider

source it. to ON / and again for OFF

you can drag time slider unsnapped
but when you mouse up it snaps to nearest time
by the way you can see a more floating animation flowable. and also can key an integer time

snapped timeslider isnt good to track animation because time steps from 3 to 4 to 5 etc.
