Property '"title"' is incompatible with index signature.

I'm getting an error with angular2-hotkeys before I'm even starting using it:

Error: node_modules/angular2-hotkeys/lib/hotkeys-cheatsheet/hotkeys-cheatsheet.component.d.ts:17:101 - error TS2344: Type '{ title: { alias: "title"; required: false; }; }' does not satisfy the constraint '{ [key: string]: string; }'.
  Property '"title"' is incompatible with index signature.

I haven't been able to figure out if it's some typescript setting being more strict in my project vs the library - but I'm at least able to continue by using 'skipLibCheck' in my tsconfig. I'd just rather not have it do that :)

Any hints?
