The typing loads between hands differs for each of the keyboard layouts. On QWERTY keyboards, 56% of the typing strokes are done by the left hand. As the right hand is dominant for the majority of people, the Dvorak keyboard puts the more often used keys on the right hand side, thereby having 56% of the typing strokes done by the right hand.

The idea is to only use one hand (preferably the left one) and type the right-hand letters by holding a key which acts as a modifier key.The layout is mirrored, so the use of the muscle memory of the other hand is possible, which greatly reduces the amount of time needed to learn the layout, if the person previously used both hands to type.
A typical 105-key computer keyboard, consisting of sections with different types of keys.

Alternating hands while typing is a desirable trait in a keyboard design. While one hand types a letter, the other hand can prepare to type the next letter, making the process faster and more efficient. In the QWERTY layout many more words can be spelled using only the left hand than the right hand.
In each case, one hand controls left/right, and the other hand controls up/down movement. A further variation is used when two players use the keyboard at the same time; for example, Gauntlet uses the combination 1QSD for Player 1, and 8IKL for Player 2.
Many keyboards do not label AltGr as such, leaving the Alt marking as in the US layout – the right Alt key nevertheless functions as AltGr in this layout, causing possible confusion when keyboard shortcuts with the Alt key are required (these usually work only with the left Alt) and causing the key to be commonly referred to as right Alt ...
The "Half-QWERTY" keyboard, invented by Edgar Matias, [2] [3] consists of only the left-hand half of a normal QWERTY keyboard, but when the space bar is held down, it switches to the right half of the keyboard, allowing a person to type with only one hand.
