TUI interface lacks arrow key navigation for slash command completion. When user types /, the completion dropdown appears, but only Tab works for selection. Arrow Up/Down keys don't navigate through the completion list.

Description

TUI interface lacks arrow key navigation for slash command completion. When user types /, the completion dropdown appears, but only Tab works for selection. Arrow Up/Down keys don't navigate through the completion list.

Expected behavior

  • Press Arrow Down to select next item in completion list
  • Press Arrow Up to select previous item
  • Press Enter to confirm selection

Current behavior

  • Completion list displays correctly
  • Tab key works for selection
  • Arrow keys are ignored (no navigation)

Code location

  • Frontend: ui-tui/src/hooks/useCompletion.ts - manages compIdx state but has no keyboard event handler for Arrow keys
  • The completion popup renders in ui-tui/src/components/appOverlays.tsx

Environment

  • Hermes TUI (not CLI)
  • Version: v0.13.0

Workaround

Use Tab to select completion (works fine), but arrow key navigation is standard UX expectation.
