Before I can agree, I would need to understand how one would select a
line in a list field from the keyboard. Via arrow keys? By typing
the text of the line in a field until the string produced a unique
match from the target field?
As you say, whether one is presently focused on the keyboard or mouse
is a major consideration. But honestly, given the choice of keeping
your fingers on the keyboard and typing a 50-character URL or
grabbing the mouse & selecting it from your browser's Bookmarks menu,
aren't you at least tempted to go for the mouse?
When my OenoLog alpha tester first saw the winemaking screen, where
activity date & time are entered by clicking on a calendar & clock,
he asked, "Couldn't you change this so I could just type the date and
time?" My response was, "Yes, I can change that if it proves to be
too cumbersome for you; but consider this:
You are entering reasonably current transaction dates & times in
chronological order. In most cases the transaction calendar will
already be showing the correct month; so you can designate date and
time in three mouse clicks...four if you have to go to the next or
previous month. It takes from 13 to 18 keystrokes to type the date
But there's more at issue than just counting keystrokes vs clicks.
Using the mouse, one may enter an incorrect date or time (eg: 9 Sept
02 10:45 when it was supposed to be 8 Sept 02 10:54); but one can
NEVER enter an invalid date (eg: 32 Sept 02 10:65). When one clicks
on a grape variety on a list, one can select chardonnay when the
grapes were zinfandel; but one cannot enter 'chardonay' or
OenoLog still captures date & time via the mouse.
I guess I'm suggesting focusing your annoyance on the programmer
whose design has you switching back & forth between mouse & keyboard
rather than on the mouse itself.
