Recording IQ - how to start and stop as there is not wav menu anymore

[Raj, N2RD]

Hello,

 I am trying to set up a 'timemachine' to record IQ off the air and play back, primarily to demonstrate receivers.  The old Thetis has a WAV menu and current one does not.  I looked at /Setup/Audio/Recording.  I cannot find a button for it?  Do I have to bind a key? What is a preferred one?

Thanks for tips and pointers,

Raj, N2RD
