- Subject: ["all"] as an Lvalue?

Hi all,
I'm writing a document on Luakit, and in my section on making fonts
bigger, I need to give instructions to edit the domain_props table,
which looks something like this:
=====================================================
domain_props = {
["all"] = {
enable_scripts = false,
enable_plugins = false,
enable_private_browsing = false,
user_stylesheet_uri = "",
},
["youtube.com"] = {
enable_scripts = true,
enable_plugins = true,
},
}
=====================================================
It looks like domain_props is a table whose two elements are each
tables, named ["all"] and ["youtube.com"] respectively. I've never seen
something like ["all"] being the name of a table element or a variable
name before. What's going on, is ["all"] an anonymous table containing
element "all"? I just don't understand this syntax, and why somebody
would do this. What am I missing?
Thanks,
SteveT
