If this is happening to you, it could be because you are using the Intel HD Graphics drivers. You’ll certainly notice this issue if you use Sublime Text since it uses the same key combination to expand the multiline editing.

To resolve the issue you can either change Intel’s keys or turn them off entirely.

  • Right click on you desktop and select Graphics Properties in the context menu.

  • Select Options

  • Either turn the hot keys off, or change their bindings.
