I am already in TeX-PDF-mode. When C-c C-c and type in pdflatex, it doesn't run. How can I run pdflatex in TeX-PDF-mode? Note: I don't change my emacs configuration file. Thanks.
| If you're using Emacs with AUCTeX in TeX-PDF-mode and finding that the `C-c C-c` command followed by typing `pdflatex` doesn't work as expected, there are a few things you can check or try:
1. **Check the Buffer**: Make sure you are in a TeX buffer (i.e., a `.tex` file). The command `C-c C-c` will not run `pdflatex` i... | [

I've been looking at a way of detecting whether point is on a comment by looking at how the current buffer is fontified.
Smartparens defines sp-point-in-comment, which relies on syntax-ppss. However, it seems that syntax-ppss and parse-partial-sexp can be used for arbitrary languages, even if they don't use s-expressio... | Yes, `syntax-ppss` and `parse-partial-sexp` can indeed be used for detecting comments and other syntactical constructs in arbitrary programming modes in Emacs. Although both functions are particularly well-known for their utility in Lisp modes (which use s-expressions), they are designed to work with the syntax rules d... | [

When writing lisp codes, sometimes I'm deep in a nested expression and all I want is to insert all the missing closing parenthesis. Right now I'm just inserting them until I get a mismatched paren, but it's not very efficient.
Is there any command to insert all the missing parentheses?

I set the Alt Gr key on my keyboard as compose key in my system (Ubuntu 14.04) in order to type letters like éóèàùçü and so on. But when I am on Emacs and try to press the Alt Gr key, I have a message saying that:
<Multi_key> is undefines
Ho can I make it work? Thanks.
P.S. as I don't have enough reputation, I cou... | To use the Alt Gr key as a compose key in Emacs on Ubuntu 14.04, you'll need to make sure that Emacs recognizes the key. The `<Multi_key>` message you are seeing indicates that Emacs is not recognizing your Alt Gr key as the compose key.
