如何在Elisp中收听Keypresses？

Question

I want to make a function that counts keyboard presses. Is there any function or hook that would let me listen to the input without modifying it?

I've tried read-event and read-char, set some variable that read input, incremented the number of keyboard presses and then inserted it into the file, but it failed. It prevents you from using any keystrokes, it also interprets keys like Backspace as a "/?", thus making it impossible to delete text.

Answer 1

找到它，你只需要使用(add-hook post-self-insert-hook #'function) ，它在每次按键后执行function 。

Answer 2

你可能想看一下post-command-hook 。
