[HOT] How to fully cover a grid square.

I ran a small mapathon at the MSF office at which we were doing task 993.
This is a vast area and a lot of the squares have not a lot in them. As
these were beginners, they were all using iD. They felt very comfortable
using the arrows to scroll through the squares, so that their scanning was
systematic. However, it is extremely slow - much slower than needed for
this task anyway.

Has anyone thought about a keyboard commend that moves the imagery, data
etc one screen (width / height) in whatever direction is pressed? I'm
estimating, but I think this would make new users two or three times as
fast in this kind of task.

One of the beginners also suggested that once a section of the task has
been viewed (i.e. has been on screen), it could then be overlaid with a
semi opaque colour, that could toggled on and off. Meaning that when a user
finishes,  they could zoom out to make sure they have covered the entire

Missing Maps has a vested interest in this as, to map large scale areas
with lots of new mappers, we want them to be mapping as efficiently as
possible. If we can double the area they can scan in any given minute,
that's a big win for us.

I'm not sure how to pursue these ideas (and the others on this thread)
further. If anyone has advice, please send it my way.
