Transpose Functions

Transposing two regions of text in a buffer means to swap their positions.

Function: transpose-items forward-item-fun backward-item-fun count

This function transposes the areas defined by the functions forward-item-fun and backward-item-fun (these functions must work in the style of forward-word and backward-word respectively).

What actually happens is that the item before the cursor is dragged forward over the next count items.

Command: transpose-words count

Uses transpose-items with each item being a word.

When called interactively, count is the value of the numeric prefix argument.

Command: transpose-chars count

Transposes characters.

Command: transpose-exps count

If the major mode in the current buffer has installed functions which define expressions then this command transposes expressions. See section Mode-Specific Expressions.
