Halo, forum members.

Which option item should I set so that I can use keyboard buttons to adjust cropped-area?

Please, see the image attached.

Thanks.

Yes. Arrows and Ctrl (or Shift or Alt) + Arrows because a single line may be moved to 2 directions and there are four lines.
Currently, they do not work, do they?

I think this feature will be useful if we do not use a mouse.


NB: The four values on the crop UI (ViewMode > Menu > Edit > Crop) is strange to me concerning with the "integration" of those four values.
e.g. With "Free" type and all part of the image is selected, the first two values can still be increased. I also do not know how th 3rd and 4th values should work when they reach their maximum values (more than the size of the image itself).

Is it because those four values do not have labels so that I do not know what each value for?

Thanks
