Hot keys….


Here is a list of hot keys I use, and what they mean (some are application-specific):

  • CTRL+ALT+BACKSPACE :: Kills the xserver and restarts it – useful if your desktop session just craps its pants and freezes up.
  • CTRL+ALT+F1…F6 :: Switches between console virtual terminals, supporting multiple logins at once – useful for when you are doing multiple things as root when you do not want to use a GUI.
  • CTRL+ALT+F7…F11 :: Switches between multiple GUI sessions – sustains having multiple folks locally logged into their desktops at the same time, great for family PCs.
  • CTRL+ALT+F12 :: Real-time kernel logs – watch ’em scroll by.
  • CTRL+<plus> :: Enlarges font size in Firefox/Mozilla.
  • CTRL+<minus> :: Reduces font size in Firefox/Mozilla.
  • CTRL+ALT+<plus> :: Increases X resolution.
  • CTRL+ALT+<minus> :: Decreases X resolution.
  • CTRL+ESC :: Starts KSystem Guard in KDE -shows the process table (similar to Task Manager in Windows).
  • ALT+TAB :: Tab through running apps, same as in Windows.
  • ALT+1..x :: Switch through tabs in Firefox/Mozilla.
  • CTRL+F1…F12 :: Switch through desktops in KDE.
  • CTRL+C :: Copy – same as in Windows.
  • CTRL+X :: Cut – same as in Windows.
  • CTRL+V :: Paste – same as in Windows.
  • CTRL+Z :: Undo – same as in Windows.
  • CTRL+Y :: Redo – same as in Windows.
  • CTRL+N :: New – same as in Windows.
  • CTRL+S :: Save – same as in Windows.
  • CTRL+A :: Select all – same as in Windows.
  • CTRL+C :: Stop a command or program running at a command line.
  • CTRL+T :: Make a new tab in Firefox/Mozilla.
  • CTRL+M :: Manage your bookmarks in Firefox/Mozilla.

And now for some MAGIC KEYS (only work if they are compiled into the kernel, but real life-savers)…

  • CTRL+ALT+SYSRQ+R :: Sets keyboard from raw mode to XLATE – very useful if your system locks out the keyboard.
  • CTRL+ALT+SYSRQ+S :: Disk sync.
  • CTRL+ALT+SYSRQ+E :: Kills all non-essential processes – doing this will nuke X, but may allo you to get to a console on F1 and reboot gracefully.
  • CTRL+ALT+SYSRQ+I :: Kills everything else except the bare essentials – may as well reboot by this time, but maybe there’s still hope…
  • CTRL+ALT+SYSRQ+B :: Boot – nope, no hope. This will appear as an unclean shutdown, and is the same as bumping the reset button on the front of your box.

Just remember, Raising Skinny Elephants Is Boring. Do it in sequence, from least spectacular to most. I think there are other keys out there, but I do not know what they are. BTW, the SYSRQ key is usually the same as the “Print Screen” key.
