A toggle light switch Internal components of a toggle switch. The toggle mechanism provides "snap-action" through the use of an "over-center" geometry. The design was patented in 1916 by William J.

The main reason for this arrangement is that the arrow keys are not ergonomic to use with a right-handed mouse. During the early days of gaming, this was not a problem as the mouse was not used; the arrow keys controlled both movement ↑ ↓ as well as looking around ← →, with strafing done using modifier keys (usually Alt + ← →).
Vertical axis mirror ambigrams find clever applications in mirror writing (or specular writing), that is formed by writing in the direction that is the reverse of the natural way for a given language, such that the result is the mirror image of normal writing: it appears normal when it is reflected in a mirror. For example, the word "ambulance ...
