Binary package hint: evolution
Evolution has a proud new feature: http://www.gnome.org/start/2.20/notes/en/index.html#rnusers advertises the "Magic Space Bar", which moves the user to the next unread e-mail, possibly in a new folder. The whole feature is making my e-mail processing much more awkward than it should be.
I keep all my unprocessed e-mail in one inbox. When I'm done with it, I delete it. Before anything lands in my inbox, it gets automatically copied to an archive folder.
What used to happen: When I process e-mail, I read it each message, pressing space to get the next windowful of text. I realize I'm at the end of a message when the text no longer pages forward. Then I pause and decide what to do: reply, forward, or put next actions on my to do list (if that sounds like GTD to you, you're right). When I've done whatever I'm going to do, if anything, I delete the e-mail (which I can safely do, since there is an automatic archive copy).
What happens now: I have to be very careful not to press space when I'm at the end of the message. Otherwise Evolution changes messages, and possibly folders from the inbox to the archive folder (which takes up to several seconds). The constant vigilance requires me to move my eyes sideways between the text and the scrollbar, which is physically tiring and probably bad, healthwise.
I think it should be possible for the user to disable the magic space bar. If there is a setting for it, I haven't found it, sorry.
Magic space bar will be switch-offable. It is hard for me to understand how a major change to the most important key in the application was not switch-offable. Anyway, see comment #18 on
