SHIFT + ENTER is sending the message instead adding a new line. To add a new line, it is incorrectly ALT + ENTER. I see no way to change this unusual behavior. Unfortunately, the CLI application cannot be used with this productively.

2. type in something
3. try to add a new line with shift + enter

Expected Behavior

Adding a new line with shift + enter

Actual Behavior
