Yes, Toad for Oracle has a Bookmarks feature.
Use Bookmarks to help you manage files. They mark a position within the Editor so that you can easily jump back to that line. You can set up to ten separate Bookmarks within one Editor.
Note: All keystrokes assume you have not altered the default Editor keys.
To set a Bookmark:
» Right-click and select Toggle Bookmark | Bookmark# (CTRL+SHIFT+# where # is a number between 0 and 9).
The bookmark number displays in the Editor gutter.
To clear all Bookmarks:
» Right-click and select Clear All Bookmarks.
To clear one Bookmark:
» Right-click and select Toggle Bookmark | Bookmark# (CTRL+SHIFT+# where # is a previously defined bookmark between 0 and 9).
To jump back to a bookmark:
» Right-click and select Go to Bookmark (CTRL+# where # is a previously defined bookmark between 0 and 9).
Note: The # must be called from the number row on the keyboard. Using the Number pad will not call the bookmark.
