Notes and keyboard

[a05sUser]

How do i add a ctrl button on my a05s keyboard without needing to use 3rd party apps (keyscafe dont have)

Aldo why is it that notes doesnt have undo button

You can't without using a 3rd party.

Notes does have an undo button- at the top on the keyboard there should be a back arrow

Sometimes there is the undo button, sometimes there isn't
