Use arrow keys to fine tune a selection

[alee001]

When entering the image editing, after using the mouse to select a range, if fine-tuning is required, you can only use the mouse to zoom in and out but cannot use the arrow keys. This operation makes it difficult to accurately trim image pixels. I hope this can be improved and added.

As shown in the example, the original image is 489x396. If you want to make minor adjustments and crop it to 488x395, you can use the arrow keys to move it to the right and down (by 1 pixel), which is much easier and faster than using a mouse.

I see few options, when selection exists:

• add new commands
  eg Ctrl+arrows - move selection 1 pixel to the direction
  pro: simple
  con: still cannot resize selection precisely or set exact size/position by entering a number

• add new toolbar
  similar to Crop toolbar
  pro: can accommodate a lot of controls
  con: it shifts image down by the height of toolbar, which is annoying
