Shift+Delete to reset an input value (in menus and settings)

[tepjz]

Are those initial base/standard values in the various settings and menus (where user can change them w/shift+arrows) stored in the firmware? If yes, how about letting shift+delete restore that value? Or, if possible, where the initial base value is always '0' (like transpose, range and the like) it would make sense? Just a thought.
