The usual method to change the values in Alias is to use the slider associated with the function. However the slider adjustment may be inadequate for small changes. You can always type in value, but then the interactivity is not there. Press ALT + LMB inside the value box and move the mouse. Moving the mouse to the left decreases the value and moving to right increases the value by the least count of the value. ( tip: Pressing ESC key while the cursor is inside the value box will clear the value )
