(I am not sure > how exactly you want to obtain the "number of words typed in today".) Ah, ok. I reread your initial message. I don't think yours is the easiest way to do that. Here's how I would do it: I would /store/ the number of words in a buffer somewhere (a buffer-local variable is one possible idea) every time the counting function is called /the first time on any given day/. This way you wouldn't have to set the counter to zero etc. - Emacs could even plot a graph showing your progress during several days? And now I'm /very/ much tempted to actually write this piece of code. It could be quite fun! It's even better. It /might/ be a good idea ot turn it into an educational blog post about Elisp or something similar. WDYT? I think I could come up with a prototype within a few days...
