Keyboards sold in different parts of the world are laid out differently from the standard US keyboard to accommodate different alphabets. Although the physical markings on your keyboard cannot change, you are able to change the symbols your keys are tied to, in effect turning your US keyboard into a Spanish or German keyboard. You will need to learn the different positions of letters on those keyboards, but it makes for easy typing and prepares you for studying abroad. 

Here's how:

1. Open the Control Panel from the Start Menu.

2. In the Clock, Language and Region section, click Change input methods.

3. On the dialog box that appears, select Add a Language. Select the language to add, and then the specific country. Different countries may have slightly different keyboard layouts even if they speak the same language. Then click Add.

4. Now look in the right corner of your taskbar. You're able to now select the keyboard layout you want to use. This will affect all programs on your computer. To change back, select English from the taskbar menu.

With a foreign language keyboard implemented, your keymapping will change to the standard layout of a German or Spanish keyboard. To know what that layout is, you can reference a Google image search, or you can enable an on-screen visual keyboard. To do this:

1. Click the Start button.

2. In the list of applications, scroll down to "Windows Ease of Access" and click it to show more options.

3.  You will see the option "Onscreen Keyboard." Click this to enable the visual keyboard.

4. If you expect to use the onscreen keyboard frequently, you can instead right click this option. Select "More" and pin it to your taskbar so that it is easily accessed in future use.
