Trigger tooltips via the keyboard

Note:

While I'm using vim mode, I can imagine this request is generic.

Use Case

I'm editing my document, and I see a red underline, I want to see the error without using the mouse to hover since it's faster, how can I do that?

Also while the cursor is under a function, how do I see it's documentation tooltip? Is there a keyboard shortcut?

[Andrew15-5]

To be clear, the de facto shortcut to trigger hover LSP action is Shift+K (in normal mode).

The fact that there is no IDE-like documentation and function signature shown on hover trigger is underwhelming. But since it doesn't exist in general (in the web app), it should be a separate feature request.
