I use a PC with a numerical keypad and have organised keyboard shortcuts for rapid highlighting using numbers. It is very convenient to select text and, by merely typing a number from 1 to 0, to have the selected text highlighted for a sequence. This works beautifully when using the numbers across the top of the keyboard but will not work using the numbers on the keypad that is integrated into the laptop keyboard.
Has anyone any comments? It's not a 'train smash'—just a little frustrating when it doesn't do what you expect!
