Key profile
The distance that the key travels when pressed — from the initial position to touching the contacts and sending the "command". Indicated as
high or low.
Keyboards with low key travel(3 mm or less) are considered to be more comfortable for fast input (such as fast typing). However, the best option largely depends on the habits and preferences of a particular user.
Key type
—
Classic type. Keyboard with keys of the usual square and rectangular shape, with a small distance between them. Such keys usually expand downwards so that the gaps between them are as small as possible.
—
Island type. Also known as "soaring" or chiclet. This is a keyboard in which each key is installed in a separate hole at a small distance from the others. Island models are more convenient than classical ones in that they are less likely to accidentally press the adjacent key. On the other hand, they are more difficult to clean: debris that has clogged into the gap between the key and the “board” itself is quite difficult to clean out, while contamination can create problems in operation.
On the practical side, the choice of a particular type of keys depends primarily on the personal preferences of the user.
Palm rest
The presence of an additional
palm rest in the design of the keyboard. Such a stand is located in the lower (closest to the user) part of the device and is a kind of continuation of the “board”, providing additional support and increasing the comfort of use. However, comfort is largely a matter of personal preference, and not all users like stands; therefore, most often they are made removable.
