Choose which editors are affected

Pick what gets dimmed

In the URLflows for Dimming popup, the Apply to selector lists four targets:

• Docs — documents at docs.google.com/document.
• Sheets — spreadsheets at docs.google.com/spreadsheets.
• Slides — presentations at docs.google.com/presentation.
• Calendar — embedded calendar views on calendar.google.com, the kind that get dropped into a site or an intranet page.

All four are on by default. Untick any you'd rather leave untouched, and the effect stops applying there while staying active on the others.

How the active editor is detected

Docs, Sheets, and Slides all live under docs.google.com, so a single content script covers all three. URLflows for Dimming reads the page's URL path to tell which editor you're in, then checks it against your Apply to choices — if that editor is ticked, the overlay is applied; if not, the page is left exactly as Google renders it.

Embedded calendars are matched by host rather than path, so they're detected the same way wherever they're embedded.

Where it runs at all

URLflows for Dimming only ever runs on docs.google.com and on the embedded calendar views under calendar.google.com/calendar/ (the embed and newembed URLs, including the /u/<n>/ variants). On every other site — including other Google products like Gmail or Drive, and the main Google Calendar app itself — it does nothing, regardless of your Apply to settings.
