By the way, plug [1], can it have a search box?

Fair.

The b2doc makes sense

"
target
    All tokens that are neither options nor properties specify what
targets to build.
"

Does it mean, it is guaranteed that single word in b2 command line
always means a target name?

And, as a target name, it is a thing specific to particular build configuration.

I'm greatful for your efforts!
