Allow user to nudge the cropshot points with keyboard

[GoogleCodeExporter]

What new or enhanced feature are you proposing?
Currently, the cropshot rectangle has to be drawn with mouse only. 

This does not allow precise placement of the two points (start-finish). The 
user has to carefully control his mouse. 

Let the user use the mouse to place the point approximately in the area and 
then use the Arrow keys on the keyboard to nudge the point. When the starting 
point is at the desired spot, let the user press ENTER hey instead of 
mouse-click.

Similarly, let the user use the keyboard (Arrow keys and ENTER) to define the 
second point also.

What goal would this enhancement help you achieve?

1. User does not have to manipulate the mouse precisely: It is easier and 
faster to use keyboard for high-precision placement of points.

2. Users with shaky hands (age/disability) can draw the rectangle for cropshot 
precisely.

• Merged into: #86

Clarification:

Currently the cropshot operation is accomplished with a single 
Click-drag-release.

If the proposal is accepted, then even the mouse-based cropshot capture method 
would have to be changed to two clicks (one click for each corner of the 
rectangle)

Can you please post the URL for the beta here (or in Issue 86), so that those 
guys also can check out this solution and revert with more feedback?

Thanks!

Near perfect!

(I found that the mouse release operation indeed does not shake the mouse as I 
feared earlier. So the keys do help in precision-placement, without needing  a 
two-click capture.)

There's a small problem though: Here, we have to press SHFT+Arrow key with one 
hand (because the other hand is already engaged in using the mouse). This 
"fingering" is a little awkward. 

Suggestion: Use the CTRL key in place of SHFT key. Then the "fingering" would 
be easier with the CTRL key because of its placement vis-a-vis the arrow keys.

Thanks!
