[RWP] Listening with pre- and post roll?

[Michael Kuhlmann]

Hi to the list,

I’M looking for a feature in reaper to pre-listen edit-selections. Sorry for again comparing reaper and pro tools, but it could help to explain what I mean: 

When making edit-selections in Pro tools I would press option-cmd-arrowkeys to listen to the edit-selection including an additional amount of pre- and post-roll. From different DAWs I also know a shortcut that makes you listen your material skipping the edit-selection as if you would have deleted  it to demonstrate if the selection is precise enough. 
I checked the transport- and selection-shourtcuts of reaper and couldn’t find what I was looking for. Any help in this case would be very appreciated.

Thanks in advance and best.

Michael
