libtmux_mcp.tools.pane_tools.send_keys_batch(operations: list[SendKeysOperation], on_error: t.Literal["stop", "continue"] = "stop", timeout: float | None = None, socket_name: str | None = None) -> SendKeysBatchResult
```

Send an ordered batch of raw key/text operations to tmux panes.

Use this for bulk TUI or persistent-shell input where each item is the
same kind of low-level terminal interaction as
:func:`~libtmux_mcp.tools.pane_tools.send_keys`. For authored shell
commands that need exit status and captured output, use
:func:`~libtmux_mcp.tools.pane_tools.run_command` instead. For
repeated observation after sending input, use
:func:`~libtmux_mcp.tools.pane_tools.capture_since` with its returned
cursor.

This tool intentionally does not compose heterogeneous operations such
as send → wait → capture. Keeping the batch homogeneous preserves clear
per-operation error attribution and avoids embedding a workflow DSL in
the MCP tool surface.

## Parameters

- `operations` (list[SendKeysOperation]): Ordered raw-input operations to send.
- `on_error` (t.Literal["stop", "continue"]): Whether to stop at the first failed operation or keep attempting
later operations. Default "stop".
- `timeout` (float | None): Maximum time in seconds to allow the batch to run before aborting.
- `socket_name` (str | None): tmux socket name.

## Returns

SendKeysBatchResult
    Per-operation results with success/error counts and stop index.
