When I build a file that generates a package warning (such as the one below), activate Sublime's word wrap and place the cursor somewhere below the warning, then the Home (End) key moves the cursor to the beginning (end) of the line above the current line.
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Latin Modern Roman}
\begin{document}
