Key terms for the reader of a federated wiki.
**Attention Neighborhood**: As you browse through a wiki, some pages you visit will refer (via a *wiki reference* or *twin*) to another wiki. The attention neighborhood is the memory of those wikis. Searches are done across all those wikis.
"Attention neighborhood" is typically abbreviated to "neighborhood."
**External Link**: The ordinary WWW link you're used to. There is a little arrow 
after one to distinguish it from an *internal link*.
A green flag
**Flag**: a colored box that represents a wiki. Most importantly, the title of every *wiki page* has a flag next to it to indicate where it's from.
**Internal Link**: These are typically (but not always) written in Title Case, like: Internal Links. Unlike *external links*, your browser won't change the color of the link if you've visited it before. (The browser doesn't know what the link links to until after you click it.)
Other terms for "internal link" are "title" and "title links." That's because the Title Case link name is always the same as the title of the *wiki page* it links to.
**Lineup**: A series of *wiki pages* arranged horizontally within a browser tab.
**Neighborhood**: See *attention neighborhood*.
**Origin**: Your "home" wiki, typically the one you started at. At any given moment, the *lineup* might contain pages from non-origin wikis. They look like pages from the origin wiki, except they have a blue border.
**Reference (Wiki Reference)**: A reference to an another wiki in its entirety. It looks like this:
A reference to another wiki
The *flag* is the clue that it's a separate wiki. The clickable *title* is the name of one page in that wiki. Just viewing a *wiki page* with a reference on it brings that page into the *attention neighborhood*.
**Title (Title Link)**: An alternate name for *internal link*.
**Twin (page)**: It's common for an author of one wiki to make a copy of a page from another wiki. The wiki software remembers where the page originally came from, which allows you to compare the two, if that strikes your fancy. Visiting such a twin page puts the original wiki in your *attention neighborhood*.
**Wiki page**: one column in the *lineup*. It is the destination of an *internal link*. Typically abbreviated to just "page."
