I am using Emacs 24.1 on windows XP/7. TAB/RET key works for auto-completing in elisp mode, scratch and even ESS mode.
When I write tex file using Auctex, hitting TAB key jumps to the next line and doesn't auto-complete the input. C-i could auto-complete the input in Auctex. but it takes two keys. Any suggestions to solve this?
