octave: Commands for Text

 
 2.4.3 Commands for Changing Text
 --------------------------------
 
 The following commands can be used for entering characters that would
 otherwise have a special meaning (e.g., <TAB>, ‘C-q’, etc.), or for
 quickly correcting typing mistakes.
 
 ‘C-q’
 ‘C-v’
      Add the next character that you type to the line verbatim.  This is
      how to insert things like ‘C-q’ for example.
 
 ‘M-<TAB>’
      Insert a tab character.
 
 ‘C-t’
      Drag the character before the cursor forward over the character at
      the cursor, also moving the cursor forward.  If the cursor is at
      the end of the line, then transpose the two characters before it.
 
 ‘M-t’
      Drag the word behind the cursor past the word in front of the
      cursor moving the cursor over that word as well.
 
 ‘M-u’
      Uppercase the characters following the cursor to the end of the
      current (or following) word, moving the cursor to the end of the
      word.
 
 ‘M-l’
      Lowercase the characters following the cursor to the end of the
      current (or following) word, moving the cursor to the end of the
      word.
 
 ‘M-c’
      Uppercase the character following the cursor (or the beginning of
      the next word if the cursor is between words), moving the cursor to
      the end of the word.
