Function
KeyHook has the following two functions:
1. KeyHook prevents the impermissible, simultaneous activation of two
function keys. Also refer to Chapter 2.2.
2. Applies for Windows NT, Windows 2000 and Windows XP:
The function keys F13 to F20 and S1 to S12 issue key combinations.
Pressing the F13 button, for example, represents pressing the key
combination Shift, F1 and releasing it the key combination Shift, F1. A
different sequence of key combinations may be necessary for certain
software products (e.g. SIMATIC WinCC). Using the Keyhook – tool, the
Makecode "Shift, F1" and Breakcode "Shift, F1" are changed to Makecode
"Shift, F1" and Breakcode "F1, Shift.
In order to start the function, select the KeyHook tab control.
