When you are erasing an element from a drawing you get four options to choose from:
Erase - Erase element from database, yes, no, eraseall, ereasenone. 

Erase is erasing the element information from the database. You can have multiple element marks that are the same. Therefore the program asks you if you want to erase only this one (yes), do not erase this (no), erase all of the elements with the same element mark (eraseall), or do not erase any of these elements (erasenone). 

(New in Q4/2021) The default for the last question is set to "No" so the user does not remove the element mark by mistake.
