== Console/terminal ==
* Ctrl-Alt-Delete - shuts down computer
* Alt-Fn (F1, F2, F3, Fn) - switch to n-th console
* Alt-Left or Alt-Right - switch to next/previous virtual terminal
* Scroll Lock - locks terminal input/output - allows to read console contents when output is going too fast. To unlock, press Scroll Lock once again. Alternatively, Scroll Lock can be enabled using Ctrl-S and disabled with Ctrl-Q. Try last shortcut if your console hangs for unknown reason -it happened to me many times that I've locked it accidentaly by pressing CTRL-S.
* Shift-Page Up and Shift-Page Down - scrolls console buffer up/down. Works also when Scroll Lock is enabled. After changing the terminal (Alt-Fn) buffer contents is erased and it is impossible to scroll it.
* Ctrl-L - screen refresh
* Alt-SysRQ-S - sync all mounted filesystem. Data in buffers is immediately written to disks.
* Alt-SysRQ-U - remounts mounted filesystems read-only
* Alt-SysRQ-B -performs immediate reboot. Don't do it without syncing and unmounting as it can cause massive filesystem corruption
* Alt-SysRQ-S, then Alt-SysRQ-U, then Alt-SysRQ-B - attempts to sync all mounted filesystems, remounts them read-only and immediately reboots computer. Fastest way to reboot Linux.
* Alt-SysRQ-H - prints out list of other SysRQ functions.
* Ctrl-Alt-Escape - xkill - click an application to kill it.
* Ctrl-Shift-Num Lock will turn the keypad on the keyboard into the mouse, so you can control the mouse from keyboard. Keys / and * on the numpad select left mouse click and right mouse click respectively. Mouse click is done by 5 on the numpad.
* Ctrl-Alt-Fn (F1, F2, F3,Fn) - switches to n-th text console.
* Ctrl-Fn (F1, F2, F3,...) - switches to the nth Virtual Desktop
* Meta + "=" zooms in
