Anyone get that thing where, you take a break from digital to do something trad, make a mistake and think and think 'ctrl+z' ... except it doesn't exist?

Well for me today, new levels. I was putting a Christmas card into its envelope, and deciding which way it should face for best effect. So I took it out, swapped it around... hmm, nah, better the first way. started to fiddle with it, and then thought oh, just undo. Then stopped, confused for a split sec, because I wasn't sure how to activate the function.

Anyone else slowly becoming strange?
