how can I statistic my key press frequency and count

Question

I am try to remap my keyboard to type better.

But I need to know the frequency of each key include symbol, It will be great if include tab shift ctrl. I need all the keypress acounting not only frequency of letters appears in english words.

I am using ibus-pinyin as my input method. and archlinux, awesome wm, without kde and gnome installed. any programes could help me?

BTW: what's wrong with dvorak. http://colemak.com/FAQ#What.27s_wrong_with_the_Dvorak_layout.3F

but colemak is not fit for me too, cause I want more synmbols.

but I have to keep some numbers, 1-5 to select chinese word from ibus, you know pinyin letters frequency is not same as english letters.

1. To get the window id, run:

   $ xwininfo
   

2. Now hit your terminal window with the mouse, from the line like that:

   xwininfo: Window id: 0x1e0000f "green"
   

3. Ask xev utility to track X events of your window, logging its output.

   $ xev -id 0x1e0000f > keystrokes.log &
   

   Type in some text and get your statistics from the keystrokes.log, filtering the key releases:

   $ grep -oP '\(keysym [^,]+, \K[^)]+' keystrokes.log | sort | uniq -c | sort -rn
