vscode select configured SSH host or enter user@host

Yes, as I mentioned before, Visual Studio Code is asking you to either select a configured SSH host or enter the username and host manually.

To select a configured SSH host, you should first have previously added the host to your SSH configuration file. To do this, you can follow these steps:

1. Open a terminal window.
2. Type `ssh-keygen` and follow the prompts to create a new SSH key if you haven't already done so.
3. Add the SSH key to the SSH agent by typing `ssh-add ~/.ssh/id_rsa` (replace `id_rsa` with the name of your SSH key if it's different).
4. Edit your SSH configuration file by typing `nano ~/.ssh/config` (or create it if it doesn't exist).
5. Add the following lines to the configuration file, replacing `my-host-name` with the hostname or IP address of your remote server, and `my-username` with your username on that server:

Host my-host-name
    HostName my-host-name
    User my-username
    IdentityFile ~/.ssh/id_rsa

6. Save your changes and exit the editor.

After you have configured your SSH host, you can now select it in Visual Studio Code by clicking on the "Select Configured SSH Host" option and selecting the hostname that you just added to your SSH configuration file.

If you prefer to enter the username and host manually, you can click on the "Enter User@Host" option and type in the username and host in the format `user@host`.
