Hardware Test
Main menu key: h
A second-level entry for display, sensor, and peripheral tests. The shelf holds up to 8 entries per page — flip with [ ] or the arrow keys; number keys restart from 1 on each page. Some tools also have letter shortcuts that work from any shelf page. ESC / GO returns a child tool to the Hardware Test shelf; press it again on the shelf to return to the main menu.
