Jump between phrases with particular pattern and feed matching words to command

[Daniel Fetchinson]

Hi everybody,

I have a text file with content like this:

[example.jpg|image]
[example.pdf|document]
[another.jpg|image]
[yetanother.doc|document]

And I'd like to make vim "jump" between the 4 items back and forth via
two selected keys, for example "n" for next and "p" for previous. When
one of the items is "selected", it should be highlighted with a
background different from the default, I mean the whole item from [ to
] should have a different background. Then I'd like to be able to
press a third key, for example, Enter, which should call a vim
function with the 2 arguments given by the file name and the file
type, for example "example.pdf" and "document".

How would I go about achieving this?

What I'm looking for is a kind of browser-like behavior like
NERD_tree.vim but this is over 4000 lines of code and I couldn't
figure out how it does what it does.

Cheers,
Daniel

You can achieve the first two goals with 'j', 'k', and the cursorline setting.
