Aging:
The rank of directories maintained by \fBz\fR undergoes aging based on a simple
formula. The rank of each entry is incremented every time it is accessed. When
the sum of ranks is greater than 6000, all ranks are multiplied by 0.99. Entries
with a rank lower than 1 are forgotten.

Frecency:
Frecency is a portmantaeu of 'recent' and 'frequency'. It is a weighted rank

Common:
When multiple directories match all queries, and they all have a common prefix,
\fBz\fR will cd to the shortest matching directory, without regard to priority.
This has been in effect, if undocumented, for quite some time, but should
probably be configurable or reconsidered.
