These keys trigger diverse low-level information dumps. They are handled by the information server (is) and contains mostly kernel and core services state dumps.
Due to the copious amount of text triggered by the magic debugging keys, most of them only outputs a screen's worth of contents at a time. If you see –more–
at the bottom of the screen, you can hit the magic debug key again to continue the output.
The list of currently available magic debugging keys may be queried with Shift + F5
.
Note: Function keys are only valid from the first console (ttyc0).
