Trigger "+" command inline using "@" key

[spacec0de]

It would be really helpful to be able to trigger the "+" command inline. The best hotkey command for this would probably be "@" since we are all accustomed to using it for this context.

Understandably, not every command would be available, but it would be great for creating links (especially when stylized internal links are available). The expectation would be that it would perform somewhat similar to Google Docs.
