Blue dot on the left border
-
I went looking for this info, but didn’t find any sort of documentation. (That’s been discussed elsewhere.)
When I accidentally clicked on the left border (where line numbers are) I got a blue dot, which, in an IDE would look like a breakpoint.
What is that?
Thanks,

It’s a bookmark.
Aside from clicking in that area, bookmarks can be toggled using the menu entry Search > Bookmark > Toggle Bookmark. Or using the Search > Mark … dialog, with the ☐ Bookmark line option enabled.
You can have multiple lines bookmarked, and can use that Search > Bookmark menu to navigate between bookmarks or manipulate the marks.

This is a feature named “Bookmark”. There are many operation supported around bookmark. Refer all operation under menu “Search->Bookmark”. Hope, this helps.
