Problems with autocomplete and german keyboard layouts

Alt + Any Keypress invokes the autocomplete in GraphiQL.

On a german keyboard, the curly brace { is typed by Alt + 8.

That means that every time you type a curly brace in GraphiQL, the autocomplete will open.

The most annoying case is when autocomplete is invoked when typing something like query test {, after which you would usually want a line break. When pressing enter, would select something from the autocomplete list.

I would suggest invoking autocomplete only on a more narrow combination, like Alt + Space.

Actually, taking a closer look at the key maps, I think we should just check for the actual character typed in instead of using the keyCode, and resolve this issue easily. The primary intention for that code block is to limit the autocompletion firing for certain punctuators - such as ‘{’, ‘}’, ‘[’, ‘]’, and ‘)’. We should probably regex-match the keypresses intended to provide autocompletion for, or recognize the differences separately and prohibit them from firing autocompletion (mainly inspired by looking at some popular non-QWERTY keyboards).

Let me PR this out.
