You can use the ::pgrep dcmd for this purpose: it will give you back the
same type of output as ::ps but only for the matching names.

::map takes the value of dot (.) on the left-hand side, evals an expression
that is its argument, and outputs the new value of dot. This is useful
sometimes in pipelines (e.g. take a list of addresses and add offset 20 to
them). Here's a contrived example just to show you what it looks like:
> 100,5=Kn4+
100
104
108
10c
110
> 100,5=Kn4+ | ::map '. + 200'
300
304
308
30c
310
