Hi,
I recently got stuck in a “chunked type” mode in Sublime Text 3 when I happen to press SHIFT + SPACE at the same time. When this happens, all the text I input doesn’t show up on my screen until I press SPACE again. To disable it I have to press SHIFT + SPACE again! I am a very fast typer, so it is super annoying and is impairing my ability to program fast. I really don’t want to uninstall and reinstall because I have spent a lot of time customizing my interface and theme. 
It does not appear as a keybinding in the preferences either, so I can’t remove it. It is really impairing my ability to dish out fast code. This doesn’t happen on any other text editor and on the web. Please HELP! How do I disable this entirely???
