I hope this is the right place to send this. I usually do not want to start a new paragraph after a display equation, so I have been setting the next paragraph to \noindent using ERT.
This is quite tedious so I created a keyboard shortcut to do the job (with the help of Richard Heck). \bind "C-y" "command-sequence ert-insert; self-insert \noindent a; delete-backward; next-inset-toggle" I think this is a common problem and you should consider building it into LyX. Bob
