I'm currently working in a website of an statistical teaching material. I need to use both HTML and LateX code frequently. In windows I use Notepad++ and in Ubuntu i use gedit. Both of the software has an ability of highlighting code but I always suffer with one problem. Can i have the 'Syntax Highlighting' and 'Code Complition' for both HTML and LATEX at a time? How can i combine them together? Please anyone suggest.
