Where can I change the keyboard increment?

Hi!

Such a scenario:

1 Use the palette apperance can add a new strok to the object.

2 Now, to the stroke, I might add transformations.

3 I want to creatively find the amount of transformations. Turn to preview the changes.

4 Unfortunately, the slider is not precise and varies the size too much.

5 So I make the cursor to the field, and now controls the change of the unit using the keypad. For example,

Shift + Arrow UP or Down - increments of 10 units

Alt + Arrow UP or Down - jump by one unit

CMD + Arrow UP or Down - jump about half of the

I do work in mm, I would be more precise if I can change the pitch CMD + UP or Down Arrow to jump about 1/10 the unit?

Regards!

P.S.

When working with a palette of transformations in view of the above, it is impossible to move the cursor selected object, such as it is in Photoshop when working with a palette of effects? Such a solution would be very fast and very creative.
