Depending on the language you chose (see the section called “Choosing your Language”), DrakX automatically selects a particular type of keyboard configuration. Verify that the selection suits you or choose another keyboard layout. If you don't know which layout your keyboard has, look in the specifications that came with your system, or ask the computer vendor. You can also look here: en.wikipedia.org/wiki/Keyboard_layout
If your keyboard isn't in the list shown, click on to get a full list, and select your keyboard there. Note that after having chosen your keyboard, you will return to the first screen and it'll seem that a keyboard from this first screen was chosen. You can safely ignore this and go on, the keyboard you chose from the full list will now be configured!
If you choose a keyboard layout based on a non-Latin alphabet, the next dialog will allow you to choose the key binding which will switch the keyboard between the Latin and non-Latin layouts.
Additional information: You may have a keyboard which does not correspond exactly to your language: for example, if you are an English-speaking Swiss native, you may have a Swiss keyboard. Or if you speak English and are located in Québec, you may find yourself in the same situation where your native language and country-set keyboard don't match. In either case, this installation step will allow you to select an appropriate keyboard.
