使用 tmux 发送原始密钥？

tmux 有send-keys一个非常有用的命令。这个命令的一个特性是它“按你的意思做”，比如允许你ENTER使用发送tmux send-keys。这或许是个不错的 hack，但它让我在编程中使用时感到紧张。

有没有办法指定以“原始”模式发送键，以便“ENTER”不会转换为换行符？

我看了一下手册，没有看到选项：

       send-keys [-FHKlMRX] [-c target-client] [-N repeat-count] [-t target-pane] key ...
                     (alias: send)
               Send a key or keys to a window or client.  Each argument key is  the  name  of  the  key
               (such as ‘C-a’ or ‘NPage’) to send; if the string is not recognised as a key, it is sent
               as  a series of characters.  If -K is given, keys are sent to target-client, so they are
               looked up in the client's key table, rather than to target-pane.  All arguments are sent
               sequentially from first to last.  If no keys are given and the command  is  bound  to  a
               key, then that key is used.

               The -l flag disables key name lookup and processes the keys as literal UTF-8 characters.
               The -H flag expects each key to be a hexadecimal number for an ASCII character.

               The -R flag causes the terminal state to be reset.

               -M  passes through a mouse event (only valid if bound to a mouse key binding, see “MOUSE
               SUPPORT”).

               -X is used to send a command into copy mode - see the “WINDOWS AND PANES”  section.   -N
               specifies a repeat count and -F expands formats in arguments where appropriate.

一种解决方法是将每个字符作为单独的参数发送，以便通过编程使用。我使用了tmuxp Python 库，它很可能解决了这个问题，同时提供了完整的 API。但我想在 Shell 中执行此操作。
