The Lazarus IDE has an optional file overview feature called an "overview gutter". This gutter is the thin vertical bar adjacent to the source editor's vertical scrollbar. You can show or hide the overview gutter via the "Show overview gutter" checkbox found on the IDE Options dialog's Editor / Display page (the fourth checkbox in the "Margin and gutter" groupbox).


When editing Pascal files the overview gutter shows a compressed summary of line and unit information:

  • modified lines: green/yellow
  • left-gutter marks: breakpoints (red), bookmarks (blue), compile errors (orange)
  • interface/implementation/finalization sections are shown in various shades of grey
  • the location of the current editor page relative to the rest of the edited file is shown in another shade of grey

If you click on a rectangular coloured mark, you jump to the relevant location in the text.
