You need to add to the `insert-pair-alist' variable the pairs
corresponding to those keys.  For example:

(add-to-list 'insert-pair-alist '(?* ?*))
(add-to-list 'insert-pair-alist '(?$ ?$))
(add-to-list 'insert-pair-alist '(?% ?%))

insert pair doesn't work with *, $ and %

Hi

For a special mode I'd like to have key bindings duplicating various
characters like e. g.

(global-set-key "\C-c{" 'insert-pair)

this does work as expected (I'm getting a pair of {} and the point is
within the pair).  But I can't get the analogous with *, $ and % to
run, I'm just getting one of these characters back and not a pair.
What am I missing here?

My first thought was that the function might look up the pairs in the
current buffer's syntax table, similar to the commands for
sexp-movement, but in fact it has it's own alist:

,----[ C-h f insert-pair RET ]
| If arguments open and close are nil, the character pair is found
| from the variable `insert-pair-alist' according to the last input
| character with or without modifiers.  If no character pair is
| found in the variable `insert-pair-alist', then the last input
| character is inserted arg times.
`----

E.g., (add-to-list 'insert-pair-alist '(?% ?%))
