What is the difference between international keyboards, ABNT and ABNT2?

Have you bought a keyboard and don’t know what ABNT and ABNT2 mean? We have prepared this guide for you, take a look!

The demand for computers has grown a lot in the past year due to the pandemic. More people need mice, monitors and keyboards, and the latter device can have problems when installed, for example if it is international. Some keyboards may have settings in ABNT and ABNT2, and this may be different from what the user expects. In order for you to better understand these settings, pattern differences and much more, we have prepared this special for you to understand better.

What are the keyboard standards?

Each keyboard sold in Brazil follows the model QWERTY. This name is due to the sequence of the first 6 letters of the alphabetic keyboard: Q, W, E, R, T And Yes. This model was created in 1870 by Christopher Sholes, with the intention of being a standard that aimed to facilitate typing on typewriters, since the 3 pairs of letters that make up this sequence were and are the most used in the English language.

The QWERTY layout was first introduced in typewriters.

Another pattern for finding letters on keyboards is the AZERTY, used most of the time in French-speaking countries. Its name is also a reference to the sequence of letters in the first row of keys. On the AZERTY keyboard, the Q and W keys and the A and Z keys are swapped with respect to the QWERTY and the letter M is moved to the second line.

However, outside the alphabetic keyboard there are two models sold in Brazil: or ABNT and the ABNT2. For the traumatized TCC, the name of the models refers to what you thought: Brazilian Association of Technical Standards, but instead of requiring margins and the like, it requires keyboards sold in the country to have certain symbols, such as accents, high numbers, and square brackets. The standard recommended by the Association is currently the ABNT2, but the previous model is still on sale.

There is a third model that can also be found in Brazil, the International. The model of arrangement International English (US) keyboard differs from Brazilian standards by not having the “Ç” key and also by having the key log into smaller than the others layout.

What are the differences between the models

At first glance, there aren’t many differences between the two keyboard standards sold in the country. The layout of the keys on both is the same, both for accents and for letters and numbers. However, on keyboards ABNT2, there is the key Alt Gr, on the right side of the space bar. This key, seen by many as a “dead space” on keyboards, actually has very interesting functions.

Alt gr and the abnt and abnt2 schemes
The Alt Gr key, located next to the space bar, is the main difference between the two models.

When the Alt Gr is pressed with a key that has a third function, it is possible to type symbols that do not have a key of their own. The secondary function of a key becomes active when it is pressed with the key TO SHIFT, while the third function is only accessible with Alt Gr. However, it is interesting to note that keyboards are just physical devices, which rarely rely on any kind of internal software. This means that the settings of which pattern it is can be changed by the operating system, with the keyboards of one pattern being used as if they were the other pattern, with no problem.

Some of the characters that can be typed with the key Alt Gr are as follows:

  • ¹ – pressing Alt Gr and pressing the “1” key;
  • ² – pressing Alt Gr and pressing the “2” key;
  • ? – pressing Alt Gr and pressing “3”;
  • ns – by pressing Alt Gr and pressing the square brackets key ([ e {);
  • º – ao pressionar Alt Gr e apertar na tecla de colchetes e chaves (] And });
  • § – pressing Alt Gr and pressing the equal and positive key (= and +);
  • / – by pressing Alt Gr and pressing the “Q” key;
  • ? – pressing Alt Gr and pressing the “W” key.

Finally, on the international keyboard, the differences lie in the position of some keys, with the caret “^” next to the “6” key and the tilde (~) next to the back letter (`), in a single key, which is next to to the number “1” at the top of the keyboard.
