-anewer file
File was last accessed more recently than file was modified.
Does find change any of the three stat(1) times? Not for -type f at
least I'm sure, so my line is still useful.

I was trying to find all the .debs in /var/cache/apt/archives that I
had just copied in via cpio, but hadn't yet installed.
Installing would update their access time, so I could use ! -cnewer (or
was it ! -anewer, I forgot) to find which ones' ctime was newer than
its access time. (So indeed ! -cnewer, but the {} idea applies to both.)
Wait,
-cnewer file
File's status was last changed more recently than file
was modified.
So what I want is -cnewerthanaccess, so there should be a more general
way to write an expression to compare any of the three stat(1) times!
-cna -coa -anm -aom ...(newer/older) ... 3 x 3 x 2 ? or perhaps just
half (newer only)... and allow {} in the target position!
