This tip is unlikely to free up hours of your time, but it will make
your keyboard finger-pecking faster while composing an email, SMS,
OneNote entry or suchlike. Rather than pressing the numeric or
punctuation buttons to enter their respective modes, then choosing your desired digit or mark, then
tapping the button you first pressed to get you back into the standard
keyboard, just press and hold the numeric/punctuation button and slide
your finger over to the number or mark you want to use. Release your
finger and the keyboard will snap back into default keyboard mode. Ninja
skill unlocked.
