I browsed Emacs source repository and found strokes.el package.
This is very awesome but I found a bug.

When two or more strokes are defined including string returning strokes, 
M-x strokes-list-strokes causes an error.

Reproduce steps:
1. emacs -Q
2. M-x strokes-global-set-stroke (and define a stroke and corresponding command(emacs-version))
3. M-x strokes-global-set-stroke-string (and define a stroke and corresponding string(emacs))
4. M-x strokes-list-strokes => error message
;; when (setq debug-on-error t)
Debugger entered--Lisp error: (wrong-type-argument symbolp "emacs")
  symbol-name("emacs")

Why use prin1-to-string?

Actually, since string-lessp accepts symbols, an easier fix would be to
just drop the calls to symbol-name.

That’s simply because I imitate the code in strokes-list-strokes function.

Thanks for the advice! I made another patch and checked this  works well.
