The Code Explorer dialog is reached from the Lazarus IDE Main Menu > View > Code Explorer menu item.
Overview
The Code Explorer dialog has two tabs: Code and Directives. The Code tab shows the Pascal structure - types, variables, constants, classes, etc and the Code Observer. The Directives tab shows the compiler directives structure - $MODEs, $IFDEFs, $DEFINEs, $INCLUDEs, etc.
The Code Explorer dialog usually opens with the 'Code tab displaying the Unit name and branches for Interface and Implementation sections, but clicking on the + box to the left of any branch will open up its sub-branches, in more and more detail until individual constants, types and variables are displayed as well as procedure and function declarations. If you change the file displayed in the main Source Editor window, you need to click on the Refresh button of the Code Explorer to display the structure of the new file.
Double click on the nodes to jump to the corresponding position in the source editor.
HINT: The Code Explorer is a floating window. That means you can leave it open and switch freely between other floating windows like the source editor or the Object Inspector.
