Note down / jot down / scribble down All three phrasal verbs are described as quick writing down an information. "Scribble down" presumes that it is made in an untidy way, right? The Longman Phrasal Verbs Dictionary explains "jot down' as 'to write quickly ON A PIECE OF PAPER" while 'note down' just as quick write down an information. My questions: 1) Can 'jot down' be ONLY used when we write down information on a piece of PAPER in a quick way? 2) Can 'jot down' be used, for example, when we save information on a cell phone in a quick way? 3) Is there any difference between 'note down' and 'jot down' or they are completely interchangeable? Thank you for your time and help :)
