Missing commands?

[Yan Wong]

Hello,

Do LyX commands exist for a) cycling between open buffers in order and 
b) repeating a find command (equivalent to clicking "find next" in the 
find dialog box)? In Macintosh applications these are generally bound 
to Command-` and Command-g respectively, and it would be very useful to 
me to be able to specify these as key bindings. I'm using LyX 1.3.5 on 
OS X.

Thanks

Yan
