Windows has various Regional & Keyboard Layout settings, and these are best managed within the Windows Control panel. Changing the Keyboard in OnScreen only affects OnScreen. Proper operation of the selected layout may depend on the version of Windows, your current Keyboard Layout, and Regional (International) settings.
If you wish to change the physical keyboard layout used by Windows, you must change your Windows driver from the Windows Control Panel (available in Keyboard Properties, Layout). You may be required to have your Windows CD (or original installation media) when loading a previously unused keyboard layout.
For proper font display & typing, you may need to set Regional Settings (available in Regional Settings).
When an International keyboard is selected, OnScreen offers the option to run the Windows Control Panel.
On some International layouts, the right [Alt] key becomes a combination [Ctrl][Alt] keystroke, and may be labeled [AltGr].
OnScreen keyboard layouts include the characters displayed on OnScreen and the low-level keyboard scancodes (scancodes are the hardware level information about which key was pressed). Most keyboard layouts are similar, but if you experience improper display or incorrectly typed characters, you must verify the OnScreen layout, Windows Keyboard Properties, and Windows Regional Settings.
Font character set, AltGr handling, and the Lowercase display setting are automatically updated when required for keyboard layouts selected through OnScreen Setup. Refer to Advanced Notes on Keyboard Layouts for additional documentation.
