Completions

Default shortcut for inline completion command is ^" (control-shift-') The completion provided by copilot-language-server should appear next to your cursor position and autoselected.

Experimental feature

There is a another option to use inline completion and it's a completion by typing. This invocation happens on TextEditor.onDidStopChanging.

This mode can be enabled in Extensions > Extension Library > Copilot > Settings by enabling the Enable inline completions on typing checkbox.

WARNING: This is an experimental feature, so be careful not to lose or break your code by using it.
