This just made me laugh and I had to pass it on. IBM are doing "usability studies" for Hannover - the next release of Notes, which you knew of course.
A question was posed, to which I replied (although it appears to have been removed?), asking what should be done with the F5-locks-screen feature. Personally I think it should be dumped, as was suggested in their blog post.
The F5 button should have the same functionality as in Windows, whereby it refreshes whatever you're looking at. The fact that this functionality lies behind F9 is a constant annoyance to me. Whether or not a one key method of locking Notes is needed aside, I just don't think it should be the F5 key.
Anyway, with 90 comments to work with they went back to the usability lab, did their sums and came up with:
2 + 2 = F5 = Lock Computer.
Err. WTF!? If I want to lock my computer I'll press Windows key and L thanks all the same. If I pressed F5 expecting it to refresh the view only to find I had to unlock my computer I don't know what I'd do to the monitor. Notes has me screaming at it often enough already without other usability blunders being added.
It's a shame really. At first I thought it was great that IBM were asking us our opinions on things. Even though the majority of opinions posted seem to point in one direction they seem to be taking the other.
