Is there any way to navigate to a type declaration of a generic parameter? Right now

val foo: Foo = createFoo()

with caret somewhere in createFoo, pressing cmd + shift + b will navigate to Foo. Nice 👍

What I want is with:

val foo: Flow<Foo> = createFooFlow()

with caret somewhere inside createFooFlow to navigate to the generic parameter, Foo, instead of Flow. Is there a shortcut for this, or any other way to easily navigate to Foo?

I guess you are asking this because you are inferring the type? I haven't tried, but if type hints are not clickable, this can be a feature request

Yes exactly, I added types in the examples for clarity.

I found myself navigating to wrapped types more and more often and hoped there’s a shortcut or some trick available

I opened https://youtrack.jetbrains.com/issue/KT-46116 but I forgot there’s KTIJ project, oh well

Well, technically there isnt "the" generic parameter so there is the question of what happens in the multiple case.

[wasyl]

Yeah, I’m aware it’s not that simple. A dropdown would be reasonable I suppose

And what about nested type parameters? <String, Array<List<String>>>?
I’d say an expandable dropdown could solve that:

+---------------+
| String        |
+---------------+
| Array       ->|
+---------------+
