Networking :: Network disconnect is freezing my systems - v4.1
It depends on your keyboard, not software. It's either it's own key, usually next to Print Screen, or combined with a key, again usually Print Screen.
For example on the laptop I'm on currently it's combined with print screen, and used as alt + printscreen.Thanks curaga! I found it. All these years, I've been wondering what that does.
OT: Anybody know what the "Scroll Lock" does?

sysrq + s = emergency sync sysrq + u = emergency umount
What is emergency sync?
Does emergency umount unmount everything?Emergency sync is just a sync that has highest priority, and emergency umount unmounts everything it can, and remounts the rest read-only..
In Linux Scroll Lock is the equivalent of windoze's "Pause/Break". It pauses the current program, and pressing again lets it continue. Try catting a large file, for example It also has some use in some spreadsheets, even MS excel..Thanks curaga,
