On a several occasions I have lost the ability to press Command + Left and Right to go to the beginning and ends of lines.

I never modified the default keymap. How do I recover this functionality?

Thanks!

I also searched my entire sublime folder for “command+left” and it only found the warning about these coming from the system.

All other programs command+left still works.

Seems to result from copying packages from one computer to another. If I take a bunch of packages from my laptop, drag them to dropbox, drop them in Packages on my desktop, the desktop loses this keybinding.

Let me know what you guys think.
