I often use
gf as supported by Vim or with the help of plugins like
rails.vim as a way of quickly
navigating to existing files. For unloaded files, this loads a buffer with
the cursor at the top of the buffer. For existing buffers, it opens to that
buffer with the cursor where it was when you left.
Vim also supports a slightly fancier goto file command,
gF. If this
command is used while the cursor is over a file with a line number appended
to the end, it will not only open up a buffer with that file, it will move
the cursor to the specified line number.
With this repository, I could try it out by moving the cursor over the
following text and hitting
This will open up a buffer for
README.md with the cursor at line 100.
:h gF for more details.
