Силовые структуры
The way the keys are arranged on the keyboard may make typing easier as well. Traditionally, keyboards are staggered, with one row of letters slightly offset from the row beneath it. Columnar keyboards arrange the keys in a grid of rows and columns. This style takes a little getting used to, but some people find it allows them to type faster. You can also make the keys of some keyboards do more than just produce letters. Programmable boards let you map shortcuts and other functions, including macros, which may keep you from reaching for the mouse quite so often, saving you time and possibly strain as well.
