two dollar signs in insert mode in VIM

Question

When I type two dollar signs $$ in insert mode in VIM it changes the text to $$<++>. What does this mean? And how do I make it no longer do this?

Answer 1

This is a place holder inserted by the latex-suite plugin. You can jump to it with <C-j> (Ctrl+J).

see "Place Holders" section here: http://vim-latex.sourceforge.net/documentation/latex-suite/latex-macros.html

Answer 2

Sounds like the latex-suite plugin (or something similar). Use :scriptnames to see which plugins have been loaded.
