In VSCode, if you would prefer that Github Copilot only suggests completions when you explicitly trigger them instead of as-you-type (which often interrupts my flow), ensure that the setting github.copilot.enable has an item *: false so it does not enable for any filetypes, and then use Alt+\ (alt-backslash) to trigger a completion when you actually want it.
You can also bind an alternative keyboard shortcut to editor.action.inlineSuggest.trigger if you don’t like Alt+\.
