[Feature request] Keyboard shortcut for "Add field"

Description

When in "Symbol Properties" adding fields, it's possible to type the field name, press tab to go to the field value, and type the field value. However, to add another field, I have to move my hand back to the mouse and click "Add field". It would be great if this function could be bound to a keyboard shortcut. I checked in Preferences -> Hotkeys, but I didn't see it. I also checked the documentation.

Even better would be if when pressing "Enter" in the field value, it would automatically add a new field and place the cursor in the field name. If you don't type anything in the field name when the text input is unfocused, the field is deleted.
