<p>I think what I would like the feature to be... I tried with
Inkscape and it works in the same way: arrow keys doesn't make
objects snap to grid. Only mouse does. Arrow keys would be used
for precise position.</p>
<p>Shift-Arrow-Keys would not snap to grid. Again, they are for move
objects faster and then, without Shift, precise position.<br>

<pre>Hi all,
Since we've got a grid in editmode now, I figured it's a good time to
take the plunge and implement "snap-to-grid."
I have an understanding of the basic use case. Here's an edge case:
1. Start with a spaghetti of objects positioned at arbitrary
positions. Some may be aligned with the grid, some may not.
2. Select all.
3. Press `<rightArrow>
According to existing GUI drawing programs that have a snap-to-grid
feature, what happens in this case?
Same question for `<shift-rightArrow>`.
