If you forget the keyword shortcut you set for a bookmark, you have to find the bookmark and edit it.
It could be easier to remember keyword shortcuts if they were displayed next to the title of the bookmark in the suggestion that gets raised by typing the title in the address bar and possibly menus.
It could be accompanied by icons like 🔎 and ⭐ to represent if it is a search keyword or a regular keyword.

Similar to tags and bookmarks, there should be a dialog that can show the list of keywords.
