How does one compile a .tex file from within vim using either vim-latex or vimtex? In both cases the documentation say to 'do' \ll, but I have no idea what this means. If I press : and then type \ll I get an error (E10: \ should be followed by /, ? or &).
If I just run pdflatex on my .tex file it compiles fine, so it's not a problem with my texlive installation.
