Would be better if nano could load a ctags index, even if it only supports the 
tagname (ignore everything on line after a tab). Scan up the directory tree for 
a tags file and load if found. A syntax could also reference a ctags file 
(generated from include files) that is always loaded in addition to the one 
found. Allow the ctags command to be used multiple times in a syntax, to load 
multiple tag files. It could easily reference a dictionary file as well, and a 
symlink from a tags file (in directory tree) to a dictionary would also work.

From https://en.wikipedia.org/wiki/Ctags
"
The tags file is a list of lines, each line in the format:
{tagname}<Tab>{tagfile}<Tab>{tagaddress}
"

A later feature could add support for tagfile/tagaddress and a key to find word 
under cursor and jump to it in current buffer or open its file in another 
buffer.

And if nano's word completion walks a list it should be converted to a hash 
table before adding ctags support.
