Question about universal discriptor

I’m a new user here. After reading the tutorial of universal discriptor section, I’m so confused that why some of them are marked by “alias” while others are not

Why indeed! haha. My page with the universal descriptors doesn’t have the alias power up anywhere. Welcome to remnote, a somewhat frustrating but extremely powerful learning tool!

yeah, a little bit weired. I’m not sure whether they have some special functionality to help us use this tool better.

There is the YouTube channel with explanations of some features. Also, there is some documentation accessed by clicking the info button next to the gear in the bottom left of the screen (assuming the side bar is not hidden). Message me if you need any help.

Thanks a lot for your help!
