Remapping keys when connecting Windows keyboard to Macbook pro

Question

I recently connected my Windows keyboard to my MacBook Pro. The keyboard has a Croatian layout and I have picked "Croatian - PC" as the input language in keyboard settings. Everything mostly works fine, except for one problem. On my Windows keyboard, I would usually use Alt Gr + some key to produce a specific character. For example:

• Alt Gr + V would produce @
• Alt Gr + F would produce [
• Alt Gr + G would produce ]

But now when I connected my keyboard to MacBook pro, those combinations no longer work. For example:

• Alt Gr + V produces √
• Alt Gr + F produces ƒ
• Alt Gr + G produces ©

My question is: how can I remap those key combinations so that they're exactly the same like they were on Windows?

Alternatively, how can I find a map of the current layout to learn the new combinations? I currently don't know how to produce the @ key with my keyboard, for example, and I have to rely on copy/pasting it from the web.

Answer 1

Mac doesn't differentiate between actually pressing Ctrl+Alt & pressing AltGr. They're in effect 'the same key'.

You might be able to get something like Karabiner to differentiate, but I've never used it.

You can manually search for which keys would produce @ by opening the Keyboard Viewer - from the menu bar if it's shown, or enable it in System Prefs > Keyboard > Keyboard.
Holding combinations of modifiers will show you what is mapped to where.
