Another example: 0. emacs -Q 1. M-x list-timers * 0.1s t show-paren-function * 0.5s t # I wonder how users are supposed to know what function it is? Searching by the delay number 0.5 reveals this lambda comes from (setq jit-lock-context-timer (run-with-idle-timer jit-lock-context-time t (lambda () (unless jit-lock--antiblink-grace-timer (jit-lock-context-fontify)))))
