Regarding the issue of clearing the send bar

I have already changed the shortcut key for sending commands in the send bar to Enter. How can I set it to automatically delete the sent command in the send bar after sending? It's cumbersome to manually delete the sent command every time before proceeding with the next operation.

No file or test is named. Start by locating the send bar and the Enter shortcut handling, then trace what happens to the input after a command is sent. Done means the sent command is automatically removed from the send bar and the next command can be entered without manual deletion.
