Is there an easy way to highlight or find out which object is being passed as the receiver in IDEA? In my usual cases I can easily have ten nested scopes

you can do CTRL-SHIFT-P with the caret within the block, which will give you the type of the lambda

latest plugin has hints for lambdas <https://blog.jetbrains.com/kotlin/2018/01/kotlin-1-2-20-is-out/>

but I'm not sure if it also works for `this`

The case is something like this:
```
foo { // this: Foo
bar { // this: Bar
baz { // this: Baz
moo()
}
}
}
```
`moo()` takes something as receiver that either `Foo`, `Bar` or `Baz` satisfies. I would just like something nice like Ctrl + B for variables but since I cannot select the receiver then I cannot use that.

doesn’t CTRL-SHIFT-P work for you? I’d thought if you put the caret before `moo()` you’d see something like `Baz.() -&gt; Unit`

Yes but the receiver of moo can also be `Foo` or `Bar`. Consider `fun CharSequence.moo() {}` and `interface Foo : CharSequence`
