"!" "^"

Use '!' to repeat the last command typed at the keyboard or '!command'
where 'command' is the most recent previous command to repeat it.

Use '^' to replace a string from the last command with a new string.
The syntax is the same as in csh: "^old-string^replacement"

Examples:

  > tell ark Hi there, how are you?
  No-one by that name here.

  > ^ark^arkane
  You tell Arkane, 'Hi there, how are you?'

  > ^you^you doing
  You tell Arkane, 'Hi there, how are you doing?'

  > !
  You tell Arkane, 'Hi there, how are you doing?'

  > !tell
  You tell Arkane, 'Hi there, how are you doing?'
