The keyboard is not always good. You can take the opportunity to study the key frequency.

It may not be advantageous to have the keyboard dirty. You can take the opportunity to study the key frequency. Keyboard close-up, which key is used more, and which key is pressed less, it is clear at a glance.

 

 

 

 

 

 

A to Z 26 primary keys, upper and lower left Optical Mark keys, all bald, can be seen with a high frequency; peripheral enter, space, and backspace), Ctrl, shift, tab, ESC, comma (,), and period (.), semicolon key (;), are also the use of high frequency keys; number keys are more unexpected, 9 and 0 use frequency is very high, 1 key is also commonly used, other less use; F1-F12 each function key, f5 and F7 are the most common keys. Del, end, and Pagedown are also common keys. In addition, they are all desolate and seem to have no fingers to visit for a long time.

 

Reflect me (liigo)ProgramThe buttons for member identity include: semicolon key, parentheses key (and), that is, 9 and
0), F5, F7. The semicolon key is not unexpected. C/C ++CodeThe line ends with it. F5 and F7 are not surprising. F5 is the debugging and running hotkey in easy language and Vc, And the breakpoint hotkey in Delphi. F7 is the compilation hotkey in VC; I was surprised to hear that the two parentheses are so often used. Are there so many parentheses in the program code? We can say that braces/braces are also quite a lot in the C/C ++ code, f8/F10/F11, F8 is the single-step tracking hotkey in easy language. F10 and F11 are the single-step tracing and single-step tracing entering the hotkey in VC, which are also frequently used, but not on the keyboard.

 

In the end, I want to say that my keyboard is not actually as dirty as it is in the picture. lenses and pictures often deceive the eyes of good people. I know that you won't trust the previous sentence easily, even if it is a fact. Okay, I admit it is a bit dirty. I need to find a chance to clean it in the future.
