find-replace shortcut

[Rodrigo Fresneda]

Hi, can anyone tell me how to bind a keyboard key to the find-replace 
function? The following used to work in lyx-1.4, 
\bind "F3"      "find-replace"
but now  in (lyx-1.5.3svn) it doesn't work anymore. Incidently, the command 
minibuffer doesn't give a clue.
thanks,
rodrigo.
