# tmux_buffer:paste/3

- **Package:** libtmux_erlang
- **Language:** Erlang
- **Kind:** function
- **Source:** https://github.com/libtmux/libtmux-erlang/blob/d1b6308440cf9eb8f6647e7ae434bce60e849368/apps/libtmux_erlang/src/tmux_buffer.erl#L167

```
paste(Pane, Buffer, Options)
-spec paste(tmux_model:pane(), target(), paste_options()) ->
               {ok, tmux_operation:completed()} |
               {error, map()}.
```

Send a named buffer or latest to a registered pane. Defaults preserve payload bytes: LF separators and unsanitized input. On tmux 3.7+, raw paste uses -S; sanitize=true selects its safe print encoding. Earlier releases reject that request with unsupported_capability before dispatch.

separator is NUL-free; delete removes the buffer after the native paste call.
bracketed adds markers only if the target has enabled that terminal mode.
Native input-off/dead-pane behavior still applies. Completion establishes the
tmux command result, not consumption by the child. No automatic retry occurs.

## Parameters
