Transpose two characters (transpose-chars).
Transpose two words (transpose-words).
Transpose two balanced expressions (transpose-sexps).
Transpose two lines (transpose-lines).
The common error of transposing two characters can be fixed, when they are
adjacent, with the C-t command (transpose-chars). Normally,
C-t transposes the two characters on either side of point. When given
at the end of a line, rather than transposing the last character of the line
with the newline, which would be useless, C-t transposes the last two
characters on the line. So, if you catch your transposition error right
away, you can fix it with just a C-t. If you don't catch it so fast,
you must move the cursor back between the two transposed characters before
you type C-t. If you transposed a space with the last character of
the word before it, the word motion commands are a good way of getting
there. Otherwise, a reverse search (C-r) is often the best way.

M-t transposes the word before point with the word after point
(transpose-words). It moves point forward over a word, dragging the
word preceding or containing point forward as well. The punctuation
characters between the words do not move. For example, ‘FOO, BAR’
transposes into ‘BAR, FOO’ rather than ‘BAR FOO,’.
C-M-t (transpose-sexps) is a similar command for transposing
two expressions (voir la section Expressions with Balanced Parentheses), and C-x C-t
(transpose-lines) exchanges lines. They work like M-t except
as regards what units of text they transpose.
A numeric argument to a transpose command serves as a repeat count: it tells the transpose command to move the character (word, expression, line) before or containing point across several other characters (words, expressions, lines). For example, C-u 3 C-t moves the character before point forward across three other characters. It would change ‘f∗oobar’ into ‘oobf∗ar’. This is equivalent to repeating C-t three times. C-u - 4 M-t moves the word before point backward across four words. C-u - C-M-t would cancel the effect of plain C-M-t.
A numeric argument of zero is assigned a special meaning (because otherwise a command with a repeat count of zero would do nothing): to transpose the character (word, expression, line) ending after point with the one ending after the mark.
