Hello, pressing f1 is very useful to read available shortcuts quickly. However, it's sometimes hard to listen to all at once, so what would be nice is if shift+f1 was pressed, it opens a list containing shortcuts one by one.

This is an excellent idea. Sometimes its rather tedious to listen to the entire list of commands when you're looking for something in particular, and that something happens to be right in the middle so the history field also takes a while to find it.
