Most of my GNU Emacs learning time has continued to be spent writing
elisp. I am very slowly starting to retrain myself on a couple of
basic keystrokes: M-g M-g (goto-line) and M-% (query-replace) are
two biggies, because my use of ido-ubquitous mode actually means that
my default use of M-x to get to both of those is disrupted—the
minibuffer no longer autocompletes in the same way, so if I'm going to
have to relearn how to get to them, I should really re-learn the short
versions.
Anyway, I did want to take a moment to sing the praises of the GNU Emacs
Help facility, because it has been invaluable. Specifically
C-h f (describe-function) and C-h v (describe-variable). While the
help they give is necessarily brief, it's often enough for someone like
me, who just needs a gentle prod about something now and again. I even
used C-h f to look up the documentation for if a few minutes ago,
because I couldn't remember if you had to do progn to do a
multi-statement else block.
So that's it for today. Learn the rich set of commands that let you get right to what you need in the documentation—it will be invaluable for exploring emacs.
