On the left we have Emacs PDF viewer, which doesn’t produce as good quality images as a proper viewer but it’s good enough for these purposes, and on the right we have my highly tuned LaTeX editing environment based around AUCTeX and CD-LaTeX mode. C-c C-c y RET saves and compiles the LaTeX and the display on the left automatically updates. A very efficient way to write my revision notes.
how did you manage to show pdf within emacs?
Thnx.
