Just subscribed to the rubyonrails-talk mailing list. With 180 mails/day, a reasonably high traffic list. To process this, I was thinking back of the good old "mutt" days, when it was so easy to process hundreds of mails with just a few key presses (no need to use slow mouse movements at all).

Checked it out and turns out that Gmail also has a reasonable set of Shortcut Keys. In a previous life, the 'd' was the most useful button (conveniently positioned under the left middle finger, base row). With gmail, that will now be "x#" (select and delete), a little less convenient than 'd', but still much better than using a mouse to select and delete. I did not see the option of reassigning shortcut keys.
