Alt+SysRq+D not documented

[bbjimmy]

Apparently Alt+SysRq+D drops one to kdl but is not documented.

It should be included in ​https://www.haiku-os.org/guides/troubleshooting/ and ​https://www.haiku-os.org/docs/userguide/en/keyboard-shortcuts.html#general so that when a dev says " drop to kdl and take a backtrace," a newbie can find out how to do just that.

That's ​https://www.haiku-os.org/guides/troubleshooting/ and ​https://www.haiku-os.org/docs/userguide/en/keyboard-shortcuts.html#general

To be honest, you can find it here, as well as syslog location and other things. It is the first link in troubleshooting guide but I guess that is not easy enough to find for shy newbies.

maybe make links from those two documents to : ​https://www.haiku-os.org/documents/dev/welcome_to_kernel_debugging_land/ to make it easier to find.

I am in the progress of moving some documentation to ​https://www.haiku-os.org/docs/develop/ which allows to have a table of contents and better organized information (we're not really there, I will reorganize things better as I keep filling it with more contents). Should the info about the kernel debugger move there?

I don't think the keycombo to enter KDL should be added to the common keyboard shortcuts of the Userguide, alongside everday shortcuts like for changing workspaces. People may even try it for fun before they learn how to escape KDL with "continue"...

It's quite an advanced feature that's not important for normal OS usage.
It is, however, described where it's appropriate: in the ​Reporting Bugs topic linked from the Welcome page.

A key combo to enter KDL should be disabled in releases anyway, otherwise it would be seen as a security bug.
