The organisation (or otherwise, as some would have it) of the documentation is probably the frustration most frequently-voiced by newcomers to Inform.
There’s so much to remember that developing skills in finding one’s way around the docs and Project Index is something that will repay that effort one-hundred-fold.
With regard to your question, the difficulty is that searching the full documentation for “name” is going to throw up a a bewildering number of references, mostly not to do with the printed name
property (although as it happens, perhaps by good fortune, it currently appears in the 8th entry in the list).
One way to go about this kind of very open search is to open the thematic index of examples
in the documentation recipe book (in the current Windows IDE it’s the link at the bottom of the main index of examples on the right side of the right-hand pane when the documentation is opened), which will then open a list of all the examples (recipes) together with the ‘how to…’ they are intended to demonstrate.
Ctrl-F (or the Mac equivalent) will then allow a search of this list of ‘how tos’ for “name”, which rapidly throws up examples of changing the printed name of something.
EDIT: or, spend a few moments thinking of a narrower search term to avoid wading through a haystack of references in search of your needle: for example narrowing a search of the full documentation to “change the name” or “changing the name” instead of just “name” leads you immediately to the example “Gopher Wood” and
now the printed name of the bearded man is "Japheth";
EDIT2: or, to illustrate another approach and going back to previous comments on the Project Index, opening that and then the summary (Chart) of Kinds, then Ctrl-F “name” leads rapidly to:
object (plural objects)
Matches: value, sayable value
Objects are values intended to simulate physical things: places, people, things, and so on. They come in many kinds. The special value ‘nothing’ is also allowed, and can be used to mean ‘no object at all’.
Usually singular-named not plural-named, improper-named not proper-named.
Usually not ambiguously plural.
Can have printed name (text), printed plural name (text), indefinite article (text), list grouping key (text).
