 /* 0801: disable location bar using search
  * Don't leak URL typos to a search engine, give an error message instead.
  * Examples: "secretplace,com", "secretplace/com", "secretplace com", "secret place.com"
- * [NOTE] Search buttons in the dropdown work, but hitting 'enter' in the location bar will fail
- * [TIP] You can add keywords to search engines in options (e.g. 'd' for DuckDuckGo) and
- * the dropdown will now auto-select it and you can then hit 'enter' and it will work
+ * [NOTE] This does **not** affect explicit user action such as using search buttons in the
+ * dropdown, or using keyword search shortcuts you configure in options (e.g. 'd' for DuckDuckGo)
  * [SETUP-CHROME] If you don't, or rarely, type URLs, or you use a default search
  * engine that respects privacy, then you probably don't need this ***/
