If ELEMENT is a string or a character it gets inserted (see also
`skeleton-transformation-function'). Other possibilities are:
- \\n if not the last element of the skeleton, or not at eol,
- go to next line and indent according to mode
+ \\n go to next line and indent according to mode, unless
+ this is the first/last element of a skeleton and point
+ is at bol/eol
_ interesting point, interregion here
- interesting point, no interregion interaction, overrides
interesting point set by _
Note that \\n as the last element of the skeleton only inserts a
newline if not at eol. If you want to unconditionally insert a newline
-at the end of the skeleton, use \"\\n\" instead.
+at the end of the skeleton, use \"\\n\" instead. Likewise with \\n
+as the first element when at bol.
Further elements can be defined via `skeleton-further-elements'.
ELEMENT may itself be a SKELETON with an INTERACTOR. The user is prompted
