[Rwp] Record new item while listening to the first

[Cleverson]

Hello all, I have some past experiences with Sonar and I'm now starting 
with Reaper plus Osara. I have read the recording section in the reaper 
users' guide to try solving my question, but either it doesn't explain 
it well or the language is too visual.

On an audio track, after recording a given passage, I'd like to be able 
to record a second passage from a given point on, while reaper plays 
back the first passage. In other words, start recording a new passage 
while listening to the first passage on the same track, then the two 
passages overlap, is it possible?

Many thanks,
Cleverson
