reference-insert syntax changed?

[Jeremy Malcolm]

I have just upgraded from LyX 1.3.6 to 1.4.4, and I can't insert 
references using the minibuffer or LyX server anymore.  I used to use 
something like:

  reference-insert ref|++|label
but now LyX tells me "Unknown action".  Similar commands like 
math-insert still work.  Has the command syntax changed?  I couldn't see 
anything documented.

Thanks!
