 How to Trap CTRL+BREAK, CTRL+C on Standard & Enhanced Keyboard - Q33034
 
 The scan code for the BREAK key is &H46. The CTRL+BREAK keystroke
 combination is trapped differently, depending on whether or not the
 program is run on a standard or enhanced keyboard.
 
 For a standard keyboard, CTRL+BREAK is defined as follows:
 
    KEY n, CHR$(&H04) + CHR$(&H46)
 
 where n is in the range 15 through 25.
 
 On an enhanced keyboard, CTRL+BREAK is defined as follows:
 
    KEY n, CHR$(&H84) + CHR$(&H46)
 
 Please note that you must make separate user-defined KEY statements
 for trapping CTRL+BREAK in combination with the SHIFT, ALT, NUM LOCK,
 and CAPS LOCK keys. The keyboard flags for these other keystroke
 combinations must be added together to define a given keystroke
 sequence.
 
 See the following examples for:

    ◄Trapping CTRL+C►
 
 (when the SHIFT, ALT, NUM LOCK, or CAPS LOCK keys are NOT active).
