hey, so i had a similar problem about a year ago One of my lecturers at uni told me to try this website that sells sticker sets and keyboard covers with all the shortcuts printed on them.
So a bought a sticker set peeled them off stuck them to my keys and within a few days i was a pro!
You dont need to have the hassle of remembering and then after a while of looking at the shortcuts it all become second nature!
defo worth a try
