Quite logical and straightforward.
It is useful to read the manual (section 1.3):
"A command is often followed by setups or by text. Setups
are placed between brackets ([]). The scope or range of
the command, the text acted upon, is placed between
curly brackets ({})."
...
I see that my reflexes have been spoiled by years of practice with LaTeX - old
habits die hard.
Lamport (section 2.5):
"Command arguments are enclosed in curly braces { and },
except for optional arguments, which are enclosed in square
brackets [ and ]."
So I added a paragraph to
