That's what is supposed to explain with the 'default' in every zypper

It is above where it should tell that the package type has to be
specified, and which is the default, not below - IMO:

The phrasing is not very fortunate.
Seams that the man page of zypper was remade some
weeks ago, I don't
remember in which list it was announced...
The current man page, where you look at the command install, does not
] install (in) [options] <name|capability|rpm_file_uri> ...

If you position the cursor in the man page at the "install" command, and
you search for the word "pattern", you will see it first appears on the
"remove" command, not on the "install" command.
I looked for the info on how to install patterns looking on the man page
for the "install" command, and then for how to install a pattern searching
for the word "pattern" - and after I couldn't find it, I had to ask here.
If, on the man page you look for the modifiers of "install", you see:
] t, type <type>
] Type of package (default: package). See the beginϖ
] ning of this subsection for the list of available
] package types.
Again, "pattern" is not mentioned.
Thus, IMO, the man page is not good enough for a person that doesn't
already know how to use zypper.
