Hi I have a PB (hoping to upgrade to MBP soon) and I often use keyboard shortcuts in Sibelius that involve the full keyboard - including the numeric keypad. When travelling, in the past I have taken a full size keyboard along with me to use. However this is bulky and impractical at times. I find it frustrating to use the function keys as to use the numeric keypad within the PB keypad and its often even quicker to use the mouse. I have heard that simply plugging in a usb numeric keypad has the same effect as the function key - it turns off the main keys????? Is this true?
