If I can find out which keys I used most, I may create a macro for it; if I can find out which function I used most yet not binded, I can bind it to a key. This may improve efficiency. Is there a way to get these statistics knowledge?

If you use smex, the smex-show-unbound-commands command does exactly that; show the commands that you use frequently using M-x (the suggested smex binding) but have yet to be bound to a key binding.

I used to use keyfreq. It was good, but eventually I switched it off and went back to using my intuition.

You can view the last 300 keystrokes with C-h l calling the view-lossage function. Inspect the displayed buffer to see what 300 keys you last hit.

If you call describe-function then view-lossage you will see that you can also use the open-dribble-file function to start writing (record) all characters you type to a file.

  • (-1) 1. 300 is hard-coded (in function recent-keys). It is not just a default value. 2. C-h l does not tell you anything about "what keys you hit the most". It tells you only what the last 300 keys you used were.

  • (+1) Looks better. Glad you mentioned open-dribble-file.
