What does `keybindings.editor.copyCommandTitle` do precisely?

Question

When I try to test out keybindings.editor.copyCommandTitle by assigning to it a key, it doesn't seem to do anything. Is this because it does nothing?

Answer 1

When in the keybindings editor and a keybinding is focused, it copies the keybinding's command's title to the clipboard

KeybindingsRegistry.registerCommandAndKeybindingRule({
  id: KEYBINDINGS_EDITOR_COMMAND_COPY_COMMAND_TITLE,
  weight: KeybindingWeight.WorkbenchContrib,
  when: ContextKeyExpr.and(CONTEXT_KEYBINDINGS_EDITOR, CONTEXT_KEYBINDING_FOCUS),
  primary: 0,
  handler: async (accessor, args: any) => {
      const editorPane = accessor.get(IEditorService).activeEditorPane;
      if (editorPane instanceof KeybindingsEditor) {
          await editorPane.copyKeybindingCommandTitle(editorPane.activeKeybindingEntry!);
      }
  }
});
