I stepped away from the computer for a few minutes to get something to eat, and when I came back, the ‘j’ key no longer navigated downward. It now instead navigates left until it reaches the beginning of the line.
No one else was physically around the computer. Vintage mode settings appear to be fine. Restarted Sublime, OSX, etc. and still nothing.
Any ideas??
EDIT: This is on Sublime Text 2
