Special keys: Tab, Backspace, Enter, Esc

Text Terminals send characters (bytes), not key strokes.
Special keys such as Tab, Backspace, Enter and Esc are encoded as control characters.
Control characters are not printable, they display in the terminal as ^ and are intended to have an effect on applications.

Ctrl I = Tab
Ctrl J = Newline
Ctrl M = Enter
Ctrl [ = Escape

Many terminals will also send control characters for keys in the digit row:

Ctrl 2 → ^@
Ctrl 3 → ^[ Escape
Ctrl 4 → ^
Ctrl 5 → ^]
Ctrl 6 → ^^
Ctrl 7 → ^_ Undo
Ctrl 8 → ^? Backward-delete-char

Ctrl v tells the terminal to not interpret the following character, so Ctrl v Ctrl-I will display a tab character,
similarly Ctrl v ENTER will display the escape sequence for the Enter key: ^M


  Ctrl   r   Recall the last command including the specified character(s)
             searches the command history as you type.
             Equivalent to : vim ~/.bash_history. 
  Ctrl   p   Previous command in history (i.e. walk back through the command history)
  Ctrl   n   Next command in history (i.e. walk forward through the command history)
   Alt   .   Use the last word of the previous command
  Ctrl   s   Go back to the next most recent command.
            (beware to not execute it from a terminal because this will also launch its XOFF).
  Ctrl   o   Execute the command found via Ctrl r or Ctrl s
  Ctrl   g   Escape from history searching mode

Process control:

 Ctrl   C   Interrupt/Kill whatever you are running (SIGINT)
 Ctrl   l   Clear the screen
 Ctrl   s   Stop output to the screen (for long running verbose commands)
 Ctrl   q   Allow output to the screen (if previously stopped using command above)
 Ctrl   D   Send an EOF marker, unless disabled by an option, this will close the current shell (EXIT)
 Ctrl   Z   Send the signal SIGTSTP to the current task, which suspends it.
            To return to it later enter fg 'process name' (foreground).
