Method handleEnter

internal/tui/keys.go:213–257

handleEnter implements the three-way Enter dispatch. Alt+Enter inserts a newline; command-level Enter on an args-taking command advances to the arg popover (same model as Tab); plain Enter commits.

(msg tea.KeyMsg)

// newline; mid-turn Enter queues the prompt (queuePrompt); command-level Enter
// on an args-taking command advances to the arg popover (same model as Tab);
// plain Enter commits.
func (m Model) handleEnter(msg tea.KeyMsg) (tea.Model, tea.Cmd) {
	if msg.Alt {
		// Strip the Alt flag before forwarding: the textarea's InsertNewline
		// binding matches "enter", and an alt-flagged KeyEnter ("alt+enter")
		// matches no binding at all, falling through to a rune-insert no-op.
		return m.forwardToTextarea(tea.KeyMsg{Type: tea.KeyEnter})
	}
	if m.phase.active() {
		return m.queuePrompt()

	// Command-level Enter on an args-taking command advances to the arg
	// popover (same shape as Tab on a unique match).

		if c := commandByName(sel.value); c != nil && c.args != nil {
			m.setPromptText(sel.value + " ")
			return m, nil
		}
	}
	// Plain commit. Value() expands chip labels to full paste content (→ LLM);
	// DisplayValue() keeps them collapsed (→ echo + history). A popover
	// selection overrides both so a command prefix + Enter submits the full
	// command and no chips leak into a slash command.
