As soon as you open Bazecor, you'll find the "Keyboard selector" menu. In it, you can see the Dygma devices connected to your computer and choose which you want to configure.
If you don't have a Dygma keyboard, you can also use Bazecor to explore its features or prepare for your future keyboard. To do so, choose "Add a virtual keyboard" and follow the instructions.
Click "Configure" on the desired keyboard to open the layout editor. Your current setup will be displayed.
Click on the key you want to modify. You can change the key to any key you want or even add modifiers to create shortcuts, such as CTRL + V.
You can also modify the different layers using the dropdown menu at the top.
By default, the second and third layers contain all the keys missing from a 100% keyboard, but you can go further and create layers with almost any function you can imagine.
When you're done making the improvements, don't forget to click "Save changes" at the top right corner when you finish. Otherwise, the modifications won't translate to the keyboard.
Of course, this is just the beginning. Check the different articles on your left to dive deep into Bazecor.
