Is there a list of keyboard shortcuts useable in the inventory posted anywhere? I've looked but haven't been able to find it, so apologies if my search-fu is weak.

Are there keyboard shortcuts?
I guess there's 'a' 'tab' 'enter' and 'escape'

Ctrl + I brings up a quick search box. (works anywhere on the site) but that's the only keyboard shortcut I know of that is specific to this site.
