Some keyboard layouts have inverted number row. Is inverted number row more efficient? Let's answer that question.

& [ { } ( = * ) + ] % 7 5 3 1 9 0 2 4 6 ~ $ 8 ! ` # ^ @ : ; < , > . " ' a b c d e f g h i j k l m n o p q r s t u v w x y z \ | ? / _ - Programer's Dvorak Layout
Programer's Dvorak keyboard layout, has inverted number row.

Keyboard with inverted number row are: French Keyboard Layout (AZERTY), Ergonomic French Keyboard Layout (Bépo), and Programer's Dvorak .

Here's number row of conventional keyboard:

!@#$% ^&*()
12345 67890

I have tried the inverted number row, for a few weeks around 2005, but in the end i abandoned it.

One problem is that the numbers are needed often too, especially a sequence of numbers like credit cards, ID numbers, dates “2010-08-30” or if you do a lot scientific programing with code such as x^2 - 1/5 * 1.6. But now you need to press Shift for the numbers.

And if you type Chinese with pinyin input method, you need to type one of the number 1 2 3 4 about every 6 keystrokes. [see Chinese Input Methods]
