You can mark content to be excluded from exports by inserting it into a Scroll ignore or Scroll ignore inline macro. The content will still be displayed as normal within Confluence.
The only difference in how the macros work is that a line break is inserted when the Scroll ignore macro is used, and no line break is inserted by the Scroll ignore inline macro.
Once the macro is inserted, you can Edit it to select which Scroll Exporter app(s) specifically ignores the content in the export.

If you want to ignore content in Confluence, but still display it in exports, you can use the Scroll only or Scroll only inline macros.
