If you're going to implement a shortcut option, it should really be
something that makes referring to any entry easy and intuitive.
Something like nicknames that are shorter and easy to remember. inodes
are hardly that.

Since this idea seems to be targeted for interactive usage, what I do
is send the list of entries to an interactive search tool like dmenu,
rofi (what I use), or fzf.  These types of tools will show a list and
filter it as you type for quick and easy selection.  They work great
for this kind of thing.
