That is actually `t', the symbol, and
(info "(elisp) Format of Keymaps") tells you:

| ‘(t . BINDING)’
|      This specifies a “default key binding”; any event not bound by
|      other elements of the keymap is given BINDING as its binding.
|      Default bindings allow a keymap to bind all possible event types
|      without having to enumerate all of them.  A keymap that has a
|      default binding completely masks any lower-precedence keymap,
|      except for events explicitly bound to ‘nil’ (see below).

In this special case, S lets you invoke summary buffer commands from
within the article buffer.  Try e.g. S f with the article buffer
current.

Again, these are symbols.  The items are command remappings, and this is
explained in (info "(elisp) Remapping Commands").

Seems the brackets just denote symbols, ordinary keys most of the time,
like <f1>, compared to keys that are numbers internally, like "k".
