Thanks for your help. That didn't actually work for me, but it pointed me in the right direction.

The Lua console actually did nothing at first; I got an error for all commands I entered. To fix this, I needed to define the lua_console_hook() in my hooks.lua like so:

function lua_console_hook(expr)
  return "eval", expr
end

After this, I could use the console, but reload() gives me the error: "[strong "reload()"]:1: attempt to call global `reload' (a nil value)". Using dofile("/path/to/hooks.lua"), howver, works with the cavate that I need to use the full path to the file;  using ~/.elinks/hooks.lua returns "file not found".

Anyway, the dofile("hooks.lua") works. I look forward to butchering the HTML of sites more quickly :)
