"a.o."? Is that a common German shorthand, possibly anglicized?

I'm assuming - and rewrote it - that it stands for "or similar".

Possibly "among other" aka "inter alia"? Very occasionally shortened
"i.a.", although "e.g." is the _much_ more common form of much the
same thing.

Never seen that "a.o." thing.
