Warn users about non-working autocomplete, like when CTRL + Space is overridden by macOS

[Meligy]

There are scenarios where the intellisense shortcut is not working, and these are confusing to the user, so, it'll be good to guide the user what's wrong when they happen, and how they can fix it.

A key situation I've come into myself, is how on my Mac, this checkbox were checked:

This prevented CTRL + SPACE from working in VS Code. I originally suspected something was wrong with my project (TypeScript), then was confused because autocomplete was triggered some other ways (like when typing ( or using TypeScript index property syntax object["..."]). Keyboard bindings view was not able to record the CTRL + SPACE combination and I wasn't sure why. Until I did a bit of googling I found what the issue was.

It might be good if VS Code could have detected this and saved me the confusion.

Hello @Meligy, Thank you for pointing it out. So, is it overriding the functionality in globally or in the screen or only in VS code?
Kindly confirm.

Thanks
