Feature request: Add a hotkey to execute the import

[asgerjensen]

Hi, thanks for a great plugin.

I wish I could just press some button, to have it import all unknown types in the document, without having to mouse over all missing imports.

For example, Eclipse, when working with Java, has Ctrl+shift+o, (Organize Imports).

Minimal viable product, would pop up the list of possible imports to generate from the symbol under the cursor

Best version would traverse all unknowns in the document, and ask only if there is more than one option.
