keypad, it is possible to toggle between cursor movement and the input of numbers.

The CAPS LOCK key < >

This key is used to enter upper case letters. If this key is engaged, the central LED ("Caps Lock" / "< >" / "A") is illuminated on the keyboard. Pressing the CAPS LOCK key again reverses the lock (depending on the operating system).

The <Alt> key

The function of this key is program-dependent. It is always used in connection with other keys. Like the SHIFT key, when pressed alone it generally has no function. In the operating system as well as in many programs, special characters which cannot be found on the keyboard can be entered with the aid of the ALT key and commands can be generated.

The <Alt Gr> key

This key is used to enter the special characters shown on some keys as a third option. E.g. if you wish to enter the "\" character, hold down <Alt Gr> while also pressing the <ß> key.

The <Ctrl> key

This key is a control key. Like the ALT key it is only active in combination with other keys. Its meaning varies from program to program.

The <Esc> key

This is program-dependent. When working in the operating system, the current prompt entered in the command buffer will be deleted.

Windows-specific keys:

These keys only exist on a Windows keyboard as they support Windows-specific functions. The keys are:

1 stkey: between <Ctrl> and <ALT>, left side

2ndkey: between <Alt Gr> and <Ctrl>, right side next to <Alt Gr>

3rdkey: next to 2nd key
