How to show inferred TypeScript type in WebStorm?

Question

In VS2012, you can hover over a typescript variable and it will show you the inferred type. Is there a similar feature in webstorm?

Answer 1

Depending on the context, there are different ways to get type information. (Shortcuts for OS X)

1. View > Expression Type ⌘⇧P: shows a popup
2. Navigate > Type Declaration ⌘⇧B: navigates in the editor
3. If 2. does not help, I do Navigate > Declaration ⌘B and then 2.
4. View > Quick Definition ⌥Space (or ⌘Y)
5. View > Parameter Info ⌘P: shows a popup with the declaration of a function parameter
