Something like "developer", so that you can pass `jtreg -k:developer` or `JTREG_KEYWORDS=developer make test ...` when you really want to run them. I'll take a closer look tomorrow.

I don't think /manual is strictly UI but its usage is discouraged as manual tests are rarely run.  The tests for the SmartCard I/O API come to mind as they need special setup. There is one or two ZIP tests that take a long time and have historically been manual tests as a result. There are also a few tests dotted around that do not have the `@Test` tag, one needs to be working in a specific area to know about these. Introducing a new test group or a keyword for these tests could be an option.

In passing, I should mention the jdk_sctp test group. These tests may require kernel or other configuration and are deliberately not in any tier. That may be a comment for the other PR that is proposing a jdk tier4.
