AutoComplete with TAB

[Arkinetic]

Hello, how can i make the textbox accept the autocomplete suggestion by pressing TAB, i currently have sometihng like this:
private void editor_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Tab && autoCompleteMenu.Visible)
{
// Get the currently displayed suggestion
AutocompleteItem displayedSuggestion = autoCompleteMenu.Fragment.GetSuggestedItems().FirstOrDefault();

            if (displayedSuggestion != null)
            {
                // Get the text of the displayed suggestion
                string displayedText = displayedSuggestion.Text;

                if (!string.IsNullOrEmpty(displayedText))
                {
                    // Insert the displayed suggestion at the current caret position
                    textBox.InsertText(displayedText);
                    e.Handled = true; // Prevent the TAB key from moving focus to the next control
                }
            }
        }
    }
