contextual names+howto

Use these terms in links, nesting, or searches:

_user

the card of the person currently signed in (see above)

_main

the main card of the page.  Required in Layout cards, but can be used anywhere.

E.g., the main card of this page:

• [[_main]] gives us: inclusion

_self, _, +

the card's name. You can also use _ for short.

E.g., in the context of the Earth card, these refer to Earth:

• _self
• _

...and these refer to Earth+continents

• _self+continents
• _+continents
• +continents

Note that cards beginning or ending with "+" are contextual cards, and that "+address" refers to the same card as "_self+address".

_left, _right

the parts of a compound names's name.   _right is the rightmost part; _left is everything else.

E.g., in the context of Earth+continents

• _self is "Earth+continents"
• _left is "Earth"
• _right is "continents"

...and in the context of Earth+continents+image

• _self is "Earth+continents+image"
• _left is "Earth+continents"
• _right is "image"

_L, _R, _LL, _LR,  etc 

_L and _R are short-hand for _left and _right.  You can string L's and R's together to handle arbitrarily complex plus cards.

E.g., in the context of hay+bee+sea+dee

• _L is "hay+bee+sea"
• _R is "dee"
• _LL (left's left) is "hay+bee"
• _LR (left's right) is "sea"
• _LLL (left's left's left) is "hay"
• _LLR (left's left's right) is "bee"

_1, _2, _3, etc

Another way to refer to plus card parts.

E.g., in the context of hay+bee+sea

• _1 is "hay"
• _2 is "bee"
• _3 is "sea"
