I found out, that on Linux (Ubuntu) and Windows, the modifier keys are registered across keyboards. 2, what would you expect to happen with the modifier mask?ДЄctually not answered easily. 1 and a random character key on keyboard no. If you hook up two USB keyboards to your machine and you press the Shift key on keyboard no.

However, why am I so curious about that? Well I did some testing on different operating systems and I noticed the following.

The computer is then combining the key code with the modifier mask and determines the character to be displayed. For example, if you hold the Shift key while pressing another key, the keyboard is creating a report for the computer which consists of the key code in fourth byte and a 0x01 in the second byte which stands for вЂњLeft Shift key pressedвЂќ. While the last six bytes contain up to six key codes, the second byte contains the modifier mask. LetвЂ™s focus on the second byte and the last six bytes. The first two methods Im going to show you just involve using System Preferences. There are several different ways that you can change how these keys work. I found a great website, which describes the Keyboard Report Format, and it is quite simple: A message from the USB keyboard to the computer is exactly 9 bytes long. The modifier keys on your Mac keyboard are the Command, Control, Option, Shift, and also the fn key. How does that exactly work? Does the keyboard send a different key code to the computer which is then checking which character to print? In most of the cases, the character is just in upper case, but number will for example turn into special characters. Pressing a regular character key on you keyboard while holding created a different symbol on your screen.

As mentioned above, modifier keys are Shift, Ctrl, Alt and Cmd (or the Windows logo). Once the project was in an advance state I though about implementing вЂњanother layerвЂќ for me buttons and thought about simply using one of the existing keyboard modifier keys. The antique atMega8 Microcontroller is running a firmware with embedded V-USB to simulate regular USB keyboard. That button box just simply contains (as the name implied) a lot of buttons, hooked up to a microcontroller. This is great, as I have been frustrated by this for a long time. So you can, for example, swap the Alt and Windows keys on a windows keyboard, but leave them alone for your Mac keyboards. I was recently building a button box to have a physical device to control a video game. At some point, Apple added the ability for the user to configure the modifier keys differently on different keyboards. What I surprisingly learned about them, read belowвЂ¦ Keys such as the Shift, Ctrl and Alt are technically called modifier keys. Never heard of modifier keys? Maybe you didnвЂ™t, but for sure you are using them every single day. Modifier keys like Shift, Ctrl, Alt and Cmd on a Mac keyboard
