With several photos selected the box says how many its keywords are of.
A chip's x is a target as tall as the chip and 22 pt wide (it was 14 pt
square) that lights up on its own, and the chip is 4 pt narrower for it.
Taking a keyword off several photos, by the x or the chip's menu, says
which keyword left how many photos and that Edit > Undo puts it back; a
refused removal says why. Chips and their x show the keyboard focus, and
the Add keyword box says in its tooltip that commas separate keywords.
