Bookmarks
If you work with large projects, searching for files and folders can be time-consuming. For such cases, CLion features bookmarks. You can bookmark the necessary lines of code to be able to find them easier. You can also bookmark the project files and folders that you need more often than other project items.
All your bookmarks are grouped in lists in the Bookmarks tool window that you can open by selecting from the main menu or by pressing Alt+2. The tool window also shows all breakpoints that are automatically added to the dedicated list once you place them in your code.
CLion has two types of bookmarks:
Anonymous bookmarks don't have an identifier and allow you to place as many bookmarks as you want. Files and lines marked with anonymous bookmarks have a bookmark icon.
Mnemonic bookmarks allow you to create bookmarks with numbers (0 to 9) or letters (A to Z). Files and lines marked with mnemonic bookmarks have the corresponding letter or number icon in a frame.
Add bookmarks
CLion adds your bookmarks to the predefined list in the Bookmarks tool window that is created automatically and has the same name as the project. You can create more lists and set another list as default.
Add an anonymous line bookmark
In the editor, place the caret at a line of code and press F11.
Alternatively, right-click the gutter next to the line of code that you want to bookmark and select Add Bookmark.
A bookmark icon appears in the gutter next to the bookmarked line.
