Toddler Steps With Emacs

Toddling on

Since I posted about baby steps and counting org mode lines I’ve used emacs some more, found more stumbling blocks.

My Colours Changed Again! (Just Pick a Theme)

m-x customize-themes. In the last post I mentioned that colours were different between tmux-ified emacs and regular terminal emacs. Well, after a forced shutdown, a system update, and/or a reboot the non-tmux colours also looked off!

Fortunately, there’s a way to customise what theme you’re using: m-x customize-themes:

Others can be installed. Before / after:

I’m not 100% on it, but it’s an improvement.

Why does the modeline say “fly/–” ..?

After some digging in the minor mode help (C-h m) lead me to the flyspell code- in particular, flyspell-mode-line-string:

:lighter (flyspell-mode-line-string
            ;; If `flyspell-mode-line-string' is nil, then nothing of
            ;; the following is displayed in the mode line.
            ((:propertize flyspell-mode-line-string)
	       (concat "/" (substring (or ispell-local-dictionary
                                      0 2)))
              help-echo "mouse-1: Change dictionary"
              local-map (keymap
                         (mode-line keymap
                                    (mouse-1 . ispell-change-dictionary))))))

..and how do I change the dictionary?

M-x ispell-change-dictionary — continued from above! Having the actual code available to read as part of the documentation system is pretty handy- something I’d like to think comes from RMS’ involvement.

How do I insert a timestamp in org? A real timestamp, not a datestamp!

Add a prefix: C-u C-c C-. I’m not sure why it’s that way round; probably because specifying a time changes how things are presented in agenda view, by default.

On a related note:

The shop’s the way it is because it is the way it is.

What’s the subscript/superscript syntax in org mode?

superscript: ^{}

subscript: _{}

ref: melioratus’ gist

Press C-s again after first search, this will cause search to wrap back to the start.

There is also a QA on making search automatically wrap, which I haven’t implemented in my own .emacs yet.

How do I put a quote in an org file?



It is one of the structure templates. it can apparently be inserted with C-c C-, (for org-insert-structure-template), but for some reason that combo didn’t work for me- I suspect terminal issues again.

Regardless, something faster is better- because I was working on an org file for something in particular which used several quotes, I went ahead and enabled org-tempo in my .emacs:

;; org-tempo
;; quickly add blocks to org files
;; make it org-specific
;; see
(with-eval-after-load 'org
        (require 'org-tempo)

and could then on a new line enter <q followed by TAB to quickly get a quote block. Neat!

How do I quickly export from org to PDF?

C-c C-e l p (export to Latex → PDF). You could instead use C-c C-e l o to open the PDF after export. Also, the export was much quicker than a LaTeX compilation usually is, somehow!

Read more in exporting or the export dispatcher (which kinda sounds like a Jason Statham movie set in Hong Kong).

#+LATEX_HEADER. See LaTeX-specific export settings.

You can add specific options for links if you don’t like the red-boxed table of contents internal links and the green-boxed external URLs:
