This is an excellent observation! I was playing around this and I notice some inconsistent behavior. For example, if you do Tab-T + tag name + Enter, you can then escape the Tag field by doing Left + Left. But if you hit Esc after the Enter, I think there’s no possible way to escape the Tag field using the keyboard alone.
@Marie, I’m pretty sure this is buggy, unintended behavior. Do you need one of us to write a bug report, or can you take this from here?
Beyond that, I agree with Clayton that there’s no reason we should have to press Enter after Tag-T or Tag-P or Tag-D to start typing.
