This is definitely a note to myself. Doubtless everyone knows this but for some reason I can never seem to remember it so I am recording it in a post. If you're an Emacs user and your initials are not RMS, you probably have occasion to consult the Emacs manual. When I find myself in that position I most often just bring it up in my browser. That's easy because I have it book marked but it's also a little silly since Emacs has the manual built in.
Of course you can always do 【Ctrl+h i】 and then pick the Emacs manual entry but there's a better way. You can bring up the manual directly with 【Ctrl+h r】. That's almost no savings in labor but somehow it seems much quicker and easier. At least it would be if I could remember it.
