[Sugar-devel] Object Chooser (was Re: Etoys mp3 files)

[Ajay Garg]

Hi Bert.

Is there a way to do a textual search for a text across the entire code?
For example, I am trying to search for the string "Rewind" across the code,
but cannot find a single occurrence (via Ctrl-f and Ctrl-g).



Thanks and Regards,
Ajay
