[orca-list] incremental find in in eclipse

[jose vilmar estacio de souza <vilmar informal com br>]

Hi all.
I'm trying to make the orca announce the lines found by eclipse in  a 
incremental find.
An incremental find in eclipse can be activated by pressing ctrl+j or 
via menu.
My first problem  is how to identify that an incremental find was started.
Any ideas?
Thanks.
