-3. Remarks about undo					*undo-remarks*
+3. Undo blocks						*undo-blocks*
+
+One undo command normally undoes a typed command, no matter how many changes
+that command makes.  This sequence of undo-able changes forms an undo block.
+Thus if the typed key(s) call a function, all the commands in the function are
+undone together.
+
+If you want to write a function or script that doesn't create a new undoable
+change but joins in with the previous change use this command:
+
+							*:undoj* *:undojoin*
+:undoj[oin]		Join further changes with the previous undo block.
+			Warning: Use with care, it may prevent the user from
+			properly undoing changes.
+			{not in Vi}
+
+This is most useful when you need to prompt the user halfway a change.  For
+example in a function that calls |getchar()|.  Do make sure that there was a
+related change before this that you must join with.
+
+This doesn't work by itself, because the next key press will start a new
+change again.  But you can do something like this: >
+
+	:undojoin | delete
+
+After this an "u" command will undo the delete command and the previous
+change.
