how to set kate as default editor in 10.04?

[rikona]

Most of my working [non computer] txt files are stored in win format.
I prefer kate and have it set to use that format. How can I set kate
as default editor in 10.04 - preferably in all but especially in
recoll, which I use a lot? I changed both defaults.list files and
mimeapps.list to have text/plain=kate.desktop, but gedit insists on
coming up anyway. How an I get gedit to come up only when specifically
called, and kate otherwise?

Thanks,
