LIST is a symbol and defaults to `org-capture-templates' -- so

this function sets values on a list that's structured as such.

Thus, KEY is a string key. If it's longer than one character,

this function will search LIST for each successive run of

characters before the final, ensuring sub-lists exist of the
|

form (CHARS DESCRIPTION).

For example, if KEY is \"abc\", first a LIST item of the form (a
|
||
DESCRIPTION), if non-existant, will be added to the list (with a
|
||
default description), then an item of the
|
||
form (\"ab\" DESCRIPTION), before adding (KEY VALUE) to the LIST.

VALUE is the template or group header required for

`org-capture-templates', which see.
