In the script editor and also in the script editor EWO, you can set/delete a bookmark by clicking in the left-hand "gray" area in a line. This is the area in which the breakpoints can also
be displayed. The bookmark is indicated by a highlighted area to the left of the line:

These numbered bookmarks for breakpoints also show their number in the bookmark area and you can jump to a bookmark by using CTRL+<number>.
