Hello @Van, Shlesha , Thanks for using Microsoft Q&A Platform.
Sorry for the inconveniences. Looks like this is a UI issue. If you hover the curser to the right most corner in the power bash you can feel the button with label more on selecting it, we can see the menu options. I can understand it's little tricky.
However, please use the commands like ctrl+ S to save and Ctrl+ Q to close the editor. Thanks for bringing this to our attention.
If you are interested, you can provide your feedback here: https://github.com/Azure/azure-cli#reporting-issues-and-feedback
However, will forward your feedback to the product team.
I hope this helps.
Regards,
Vasavi
