EditRocket provides the concept of bookmarks for allowing users to mark lines of code, and then easily jump to the marked lines with the Next and Previous Bookmark options.
A bookmark can be added for the currently selected line by choosing the Search - Add Bookmark option. Bookmarked lines can be navigated to by selecting the Search - Next Bookmark or Search - Previous Bookmark options. The default keyboard shortcuts for next and previous bookmarks are C+J and Shift + C + J.
Bookmarks can also be added and removed by right-clicking on the line number section to the left of the editor contents.
Bookmarked lines will adjust with any insertion or deletion of lines made by the user.
Bookmarks are indicated in the text editor by a blue line number in the line number display to the left of the text in the editor.
