# `BB.TUI.Panels.Help`
[🔗](https://github.com/mcass19/bb_tui/blob/v0.3.0/lib/bb/tui/panels/help.ex#L1)

Help popup — overlay showing all available keyboard shortcuts.

Renders the keyboard reference as a single `ExRatatui.Widgets.Markdown`
widget so the content is a plain markdown string (`@help_markdown`)
rather than 50+ hand-built `Text.Line` rows. Markdown handles section
headings, bullet lists, inline code (used for keybindings), and
scroll offsets natively.

Pure function — returns a Popup widget struct.

# `markdown`

```elixir
@spec markdown() :: String.t()
```

Returns the full markdown source rendered inside the popup. Exposed
so callers (and tests) can introspect the help content without
spinning up the widget tree.

# `render`

```elixir
@spec render(non_neg_integer()) :: struct()
```

Renders the help popup as a Popup widget with optional scroll offset.

## Examples

    iex> %ExRatatui.Widgets.Popup{content: %ExRatatui.Widgets.Markdown{}} =
    ...>   BB.TUI.Panels.Help.render(0)

    iex> %ExRatatui.Widgets.Popup{content: %ExRatatui.Widgets.Markdown{content: md}} =
    ...>   BB.TUI.Panels.Help.render(5)
    iex> md =~ "## Global"
    true
