if I hover over `conn` further down I’d like it to tell me what it is

Not sure if I got you right, but hovering mouse cursor over some identifier *while holding `Ctrl`* will show short tooltip for corresponding declaration.

Unfortunately, it doesn't show type when hovering over variable declaration (only when hovering over usages).

You can enable parameter type hints, not exactly what you want but very useful occasionally.
Settings → Appearance → Show parameter name hints.
You can also configure there which hints exactly you need to be shown.

<@U0FLRRSQK> i’m not even getting that, declration made, used on next line, hover and i get nothing

In Editor &gt; General &gt; Other (section) &gt; Show quick documentation on mouse move - delay 500 ms

<@U0CP8EBRV> parameter name and type are different things :thinking_face:

In general I sometimes find it useful to see actual type of `val` without type inference. This is to make sure compiler inferred the right thing, so I only want to see it for couple seconds. That's the usecase.

<@U0FLRRSQK> Have you tried it? I'm not the one who came up with the name of the setting. It actually does this: <https://snag.gy/v0TkYa.jpg>

': Client' here is not actually in the code, it's just shown to you by IJ

Ah, so it's in `Settings → Appearance → Show parameter name hints → Configure... button (with Kotlin in top dropdown) → Show local variable type hints checkbox`. It works but overall IMHO for kotlin this is a useless feature because the whole point of type inference is to *not* show types. As mentioned I only want to see inferred types occasionally for couple seconds not all the time.

And IntelliJ provides you with toggle shortcut for the mentioned settings. The point is not to *type* the types, not not to *show* them. (I know the previous sentence is horrible writing :D)

`The point is not to *type* the types, not not to *show* them.` :point_left: haha, makes sense to me, but that's not what I want :slightly_smiling_face:

~What is the "toggle shortcut for the mentioned settings"?~

ah, it's called `Toggle parameter name hints` in `ide settings -&gt; keymap`, if assigned a decent shortcut this might be useful after all :thinking_face:
