I’ve written before about what prettify-symbols-mode can do for your buffers,
ranging from pure eye-candy to signficant readability improvements. Simply put,
this minor-mode “disguises” some strings in your buffer to look like something
else. For instance, in emacs-lisp-mode it makes lambda be displayed as λ,
and (for the next release) it’ll apply to a wide range of symbols in
(la)tex-mode too.
The only problem is that this (obviously) hides the symbol itself, and there’s
no way of revealing it other than disabling the mode. That’s usually not a big
deal, but it can get just a little annoying sometimes—specially when a mode
adds over 400 elements to prettify-symbols-alist.
In Emacs 25.1, thanks to Tassilo Horn, there’s a new variable called
prettify-symbols-unprettify-at-point. If you set it to t, prettify-symbols
will “unprettify” a symbol as long as the cursor is inside it. So you can easily
(and temporarily) reveal a symbol by just moving over to it.
My preference is to set it to right-edge which also reveals the symbol if the
point is immediately after it.
