I was trying to make it a bit better using the following loop:

for i in range(1,12)
redir! >= map
exe "silent ".(a:bang == "!" ? 'verbose' : '') . " map<F".i.">"
redir end
if map !~ 'No mapping found'
echomsg map
endif
endfor

But I get an error that map is not defined. However if I do:
redir! >= map
exe "silent map"
redir end
'echo map' shows exactly what it should. Any ideas why redir is not working in
the first place?
