This blog is supposed to be about what I’m learning and how the process of refining my use of Emacs is going, so each week I’ll be looking at what I wrote about in the past week (or perhaps earlier) and assessing how much I’ve been able to change my habits or otherwise make use of my new knowledge.
So this first week has gone pretty well—using
M-g M-g (goto-line) instead of
M-x goto-line has come up a couple of times and I’ve remembered the new way of doing things, and similarly
C-/ (undo) for undo. The change back to the prior handling of
line-move-visual hasn’t come up as much as I expected—I have a much wider terminal these days, so it’s less of an issue—but I’m nonetheless glad to have made the change back.
The one thing I’ve not internalized, and that I’m not sure I’m likely to internalize, is using
C-LEFT (left-word) and
C-RIGHT (right-word) for by-word cursor motion. The benefits versus
M-b (backward-word) and
M-f (forward-word) just don’t seem to be there—it turns out that for me, keeping my hands on home row outweighs the awkwardness of doing it all with one hand.
I’ve actually done a lot of other stuff this week, too—I’ve started using org2blog for all of my blogging (and will write about it shortly), reorganized my init process, started using
ido-ubiquitous, and a few other things. But, for this week, this is the end.
In GNU Emacs 23 the default line-movement behavior changed with regard to wrapped lines.
Not that I realized it at the time, entirely—like not realizing that I not only knew
M-f (forward-word) and
M-b (backward-word), but used them every day, I was so habituated to the prior behavior that I couldn’t articulate what had changed, I just knew something was different that was annoying me to no end.
It was only when I found a reference to
line-move-visual in the GNU Emacs Manual, that I realized exactly what it was that had changed—and, more importantly, how to change it back:
(setq line-move-visual nil
line-move-visual, when set to a value other than
nil, indicates that if there was a line on the screen, the cursor keys should move through it, even if it was the wrapped continuation of a prior line. Emacs’ prior behavior was that the cursor keys would move the cursor based on the basis of “logical lines”—that is, the lines as determined by the presence of line-ending characters. So if you had a “logical line” that spanned three lines on screen, when you hit
C-n (next-line) on that line, you ended up three lines down on screen.
If I hadn’t been habituated to this, I probably wouldn’t care—I don’t really think one behavior is significantly better than the other. But the prior behavior is what I’m used to, so I’m going to change it back.
At the same time, I’m setting
t so that when I move the cursor up and down while at the end of a “logical line”, the cursor will stick to the end of lines, no matter how long or short they are. This sort of stickiness is another behavior I’m used to at a fairly low level.
