![]() System Request is often abbreviated SysRq or Sys Req.There are four keys on majority of modern keyboards that are legacy from the ancient times of computers. You can see some of the MacBook keyboard decals on our website.ĩ. Keys that are (rather) useless but still on keyboards today There are few global brands that specializes in such products, among them Keyshorts, of which I am the co-founder. These stickers are subject to fashion, have trending colors or patterns, like Stardust or Washi tape. There is an ongoing trend for the last couple of years, especially among young people, to decorate their laptop keyboards (and whole laptops) with vinyl stickers. Photo by Dave Fischer 8. Fashion for keyboards ![]() Now you can have stylized version of this keyboard on your MacBook, using these keyboard decals. ![]() The keyboard is known for it's elongated look and abundance of modifier keys, with names such as Super, Meta, Terminal, Status and Hyper. Name "Space Cadet" came from a title of 1948 science-fiction novel by Robert A. It looks like taken straight from Star Trek. Space Cadet keyboard was designed by Tom Knight for the MIT Lisp machines back in the 70's. Some keyboards in office buildings even had mice droppings in them! How to prevent this situation? Wash your hands and clean keyboard the right way. Dirty keyboardsĭo you know that your keyboard may contain more germs than toilet seat? A study conducted by UK scientists found out that four out of 33 keyboards tested were potential health hazards, and one had levels of germs five times higher than that found on the toilet seat. Chorded keyboards are used mainly by visually impaired (Braille versions) and in situations where normal keyboard is useless.įrogPad chorded keyboard. This way you can type much more characters than there's physical keys. But how is that possible? Instead of typing one character with one key (like on the normal keyboard), in chorded keyboard you're using chords (like on the piano). These keyboards use only few keys to type full range of possible characters. As the computers took place of typewriters, the QWERTY was already a legacy that was uncritically adopted. QWERTY is also constructed that way to minimize the neighbouring keystrokes - which too - jammed the hammers. Sholes came with the idea that in order to slow people down, you need to mess with the layout. It turns out that when you would place keys in alphabetical order, people would type so fast, that the mechanical parts (so called hammers) would jam. So why keyboard starts with QWERTY and not, for example, ABCDE? QWERTY layout was invented by Christopher Sholes in 1872 for his new typewriter design (of course there was no computers these days). We tend to think that QWERTY keyboard layout is the most efficient because it's so widespreadly used. QWERTY is not the most efficient keyboard layout So when you hit the space, you're doing it at the exact time as 600,000 other people. From doing math, it turns out that in every 1/10th of a second on Earth, spacebar is hit 600,000 times. Without the space, it would be hardtoreadthisarticle, don't you think? According to this YouTube video by Vsauce, when you type, 18% of all keyboard hits goes to spacebar. Talking about the space, it's not only the longest key, but also the most used one. When you hit spacebar, 600000 people in the world did just the same In the result, japanese keyboards look like this: To do that switching, additional keys are required. Why? Because japanese keyboards require switching between latin/roman letters (called rōmaji) and japanese characters (called hiragana and kana). Space is the longest key on every keyboard, but in Japan the statistical Spacebar is much shorter than in any other place on Earth. ![]() It was established by ACNOR in the first canadian keyboard layout, which was later copied by computer manufacturers, including Apple for its French Canadian layout. The truth is, the icon graphically represent the Ctrl (Control) key and nothing more. It looks funny, because we usually tend to associate Canada with winter time (although it's the same stereotype that all Italians eat pasta only). It features the "snow mode" key, with snowflake icon next to Ctrl caption. The french canadian keyboard layout is used in french-speaking parts of Canada, mainly the Quebec region. But some keyboards in the world are really strange and look very different from what we are accustomed to. If you live in the United States, UK or - for example - Poland, your keyboard is most likely an ordinary QWERTY with nothing weird on it. We look at keyboard many times in a day and usually we don't think about how they work and why they look like they look. ![]()
