There is a way change value of vanilla.EditText by pressing up/down arrow ?
Does this have anything to do with the .formatter?
from vanilla import Window, EditText
class EditTextDemo:
def __init__(self):
self.w = Window((120, 42))
self.w.editText = EditText((10, 10, -10, 22), text='0')
self.w.open()
EditTextDemo()
