Actually, SysRq+K is the Secure Attention Key (SAK). It is the equivalent of Ctrl+Alt+Del in Windows. Basically, the intention is that, if you walk up to a computer you have access to, but don't necessarily trust, you press this key combo before logging in. You are then taken to a secure state where it's safe to enter your credentials - that is, you're not looking at some application that's pretending to be a login window (a trojan), you are actually at a login window. On Windows, this is achieved by switching to the Winlogon component. In DOS, this was achieved by forcing a reboot. In Linux, this is achieved by killing every application on the TTY (init will then typically spawn a new getty for you).
This might work in Debian, but it doesn't work in PCLOS KDE 64-bit. So it's not universal to Linux.
