The bookmark option places a bullet next to or removes a bullet from any line in a file. You can place multiple bookmarks in a file by using the Mark All function in the Find dialog box. Once a bookmark is added, you can jump to that bookmark from anywhere in a file. If you have multiple bookmarks, the cursor jumps to the very next bookmark.
Bookmarks are temporary and disappear when you close the Text Editor.
Position the cursor on the line to be marked, then press and hold down the Ctrl key and the F2 function key simultaneously.
To jump to another bookmark, click the Next Bookmark or Previous Bookmark icon on the editor toolbar or press the F2 function key.
The cursor jumps to the very next bookmark in that file.
The Find dialog box opens.
Click the Clear All Bookmarks icon on the Editor toolbar or close the editor window and reopen it.
