I would imagine the wiki[1] would be the place to look if it exists, but I don't see anything of the sort after a brief look. It shouldn't be too difficult to write something that would do what you need since Textadept has good Regexp support now. Take a look in Textadept's *modules/textadept/find.lua* for the `find` function (around line 114). The gist what you'd want to do is:

   local pos = buffer:search_next(buffer.FIND_REGEXP, regex)
   if pos ~= -1 then
     -- try another regex

where `regex` is your regex to match a function block. I'm pretty sure multi-line regex searches do not work, but you'd have to double-check. You can also use a loop to iterate over a table of regexes to try. Documentation for those functions is at

When you've written a function, you can bind it to the F3 or F4 key like so:

   keys.f3 = function() ... end
   keys.f4 = function() ... end

(You can replace `function() ... end` with a named function too, of course.)
