I’ve been discovering that the “control” key has magic powers! Control Z undoes the last action, while Control Y repeats the last action! Control + makes the font display bigger, and Control - shrinks it! This Control + option is particularly important for tired Piper eyes. I suppose this is old news to everyone else, but has been a revelation! And I also have learnt to count on my fingers and apparently that’s four things, not three, as set out in the title. ---

Close one tab, then press CTRL SHIFT T. That’s my favorite one because, inevitably, I end up closing a tab and then needing it open again, but don’t remember how I got to that tab in the first place. Do a quick web search for _keyboard shortcuts_ and you’ll find plenty of great ones to make your life easier. ---

Indeed there are so many useful pairs of do this/undo this that you might well need a shortcut to the shortcuts. ---

It’s the command key for me (on a Mac); though does not work with the “y” key.
