When editing your loop points for a sample, is there another way 
of getting the loop start 'Ls' and  Loop end 'Le' markers to appear 
in the sample edit window.

The only way I can find is by moving the end point of the loop in 
the zone window (instrument editor window) so that it is different 
from the end point of the sample.

Is there another way?

I'm using 5.3.0 on a mac btw.

I'm sure I'm missing something really obvious.
