[gentoo-misc] How do I click on a filename and cause a program to run, with the filename being passed to it?

[Michael W C. <co...@ca...>]

At first glance, Gentoo looks like exactly the file manager that I've
been dreaming of - but I'm having a heck of a time making it perform!

What I want to configure it to do is, when I click on the name of a
file in a directory pane, it should see that it's an html file (I got
that part, I think) and start up firefox (I sort of have that, I
think) and pass it the name of the selected file (not a clue).

Is there a secret documentation file that I'm missing?  I've read the
files in the docs directory (useful test data for trying to accomplish
my task), and they stop just short of being particularly useful...
