When writing/debugging code you often want to jump from where a subroutine/function is called to where it actually is . Hitting the "*" key is frustrating if the sub/func is called many times. The following mapping solves the problem. (Notice how it can be altered for other lanaguages)

nmap gx yiw/^\(sub\<Bar>function\)\s\+<C-R>"<CR>

Instructions: Place cursor over called function (normal mode) and type gx

How it works

yiw: Yank inner work to un-named register

/^\(sub\<Bar>function\)\s\+: search for sub or function followed by 1 or more spaces

<C-R>": Retrieve un-named register

<CR>: Start Search

What language is this supposed to work in? Basic??

Probably perl, which also uses sub for functions

I suggest to modify mapping: nmap gx mryiw/^\(sub\<Bar>function\)\s\+<C-R>"<CR>

thus allowing reverse jump by typing `r

I think this would be much better accomplished using Vim's excellent Ctags interface. :help ctags. Exuberant Ctags has support for Perl. --Fritzophrenic 20:03, 18 February 2009 (UTC)
