Jeffrey Bernstein made these interactive step sequencer (each block comes with an IR transmitter and receiver) that allows you to pick up and mix the order up - heck, just see the clip and you'll see what I mean.

Most would only ask once.
My notes would include the date, topic, and whatever key words, phrases, names, dates, figures, and side comments I thought might be useful. Most fellow students were somewhat appalled that they would write several pages of almost verbatim lines from the lectures and I would sketch out a couple of pages of cryptic entries. Whatever it took to jog my memory or remind me to look up later ended up in my notes. Rarely any more than that.
The bottom line is find out what works for you.
Now lecturers are using Powerpoint presentation, I guess you don't even need to decide what is important.
