Vim has some really handy features that aren't immediately apparent.
One of these is the ability to autocomplete / navigate paths - type all of the following keys while holding
f: bring up the first file or path found
n: select the next entry
p: select the previous entry
fto recurse into the selected path
wto go back up a level
You can also autocomplete a word that's contained in the current file. This can be useful for method or variable autocompletion while programming.
To show a list of autocomplete options simply press
Control + p or
Control + n as with the file paths to select the previous or next match.
