Dave Plowman (News) used his keyboard to write :
But can you update your caller list via the web using your computer
keyboard or by copying text? Doing it on a phone keypad can be a PITA.

Not really, you key in the numbers in the first instance to ring them,
the only extra effort is adding the name. If a regular caller should
ring me, I just save the number and give it a name. I rarely add any to
my call book, so minimal effort.
