+URL copying always uses the highlighted row, not the playback checks, and copies the same canonical page URL used for playback—not an expiring stream URL. It uses the terminal's OSC 52 clipboard support without external clipboard tools. Clipboard writes must be supported and enabled by your terminal and any multiplexer; Tubular can report sending the URL, but cannot confirm that the terminal accepted it. Text inputs and selectors keep `y` as ordinary input or ignore it.

 The bottom bar shows essential actions for the current context. Press `?` in normal mode—including selectors and previews—for the full reference. Scroll help with `j` / `k`, arrows, Ctrl-J / Ctrl-K, or PageDown / PageUp; `?` or Esc closes it without changing the underlying view or dialog. In text fields, `?` remains ordinary input.
 The overview groups shortcut/action rows under bold section headers such as `VIEWS AND VIDEOS`, with an empty line beneath each header. Shortcuts and action descriptions remain normal weight; the rows reflect configured bindings rather than showing internal action paths.
