M-p and M-P shortcuts are not defined. #26

Hi There! I installed latex-preview-pane with melpa. So i had a .tex buffer open (with auctex) in emacs. I wanted to preview the entire buffer, so i used m-x latex-preview-pane-mode. After doing so, a split buffer named Latex Preview Pane Welcome opened with just the welcome screen and "[loading document preview...]" Pressing M-p or M-P do nothing ( Although strangely both make the minibuffer say M-p is not defined).

Any ideas as to what I could be doing wrong? Thanks!

update - I discovered that it would output "Error running timer 'latex-preview-pane-update': (file-error "Searching for program" "no such file or directory" "pdflatex"). running M-x getenv on PATH returns 

/Library/TeX/texbin/:/usr/local/bin:/Library/TeX/texbin/:/usr/local/bin:/Library/TeX/texbin/:/usr/local/bin:/Library/TeX/texbin/:/usr/local/bin:/Library/TeX/texbin/:/usr/local/bin:/Library/TeX/texbin/:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Emacs.app/Contents/MacOS/bin-x86_64-10_9:/Applications/Emacs.app/Contents/MacOS/libexec-x86_64-10_9

In my .emacs file, I also have (setenv "PATH" "/Library/TeX/texbin/:$PATH" t).

Lastly, the output of which latex returns "/Library/TeX/texbin//latex"

any ideas?

edit: turns out there were just some issues with latex not being in my exec-path variable. However, the shortcuts still do not seem to be defined. is there anyway to fix this besides manually rebinding them in my .emacs?

Hi Nelson,

Glad to hear you worked it out -- are you still having problems with the shortcuts? You should have this line in your .emacs

(latex-preview-pane-enable)

Then just restart your emacs. Also, may I suggest the following package: https://github.com/purcell/exec-path-from-shell

It makes life easier when dealing with these path issues. You really shouldn't have to manually manipulate the exec-path in your .emacs. Also, note that the platform correct place to put new path entries is in: /etc/paths.d (on OS X)

Best, JLS
