+The user option ~cursory-presets~ holds the presets. The command

+Presets consist of a list of properties that govern the cursor type in

+They look like this:

+ :cursor-type (bar . 2)
+ :cursor-in-non-selected-windows hollow
+ :blink-cursor-blinks 10
+ :blink-cursor-interval 0.5

+#+end_src
+
+The car of the list is an arbitrary, user-defined symbol that identifies
+(and can describe) the set. Each of the properties corresponds to
+built-in variables: ~cursor-type~, ~cursor-in-non-selected-windows~,
+~blink-cursor-blinks~, ~blink-cursor-interval~, ~blink-cursor-delay~.
+The value each property accepts is the same as the variable it
+references.
+
+When called from Lisp, the ~cursory-set-preset~ command requires a
+PRESET argument, such as:
+
+#+begin_src emacs-lisp
+(cursory-set-preset 'bar)
+#+end_src
+
+The default behaviour of ~cursory-set-preset~ is to change cursors
+globally. The user can, however, limit the effect to the current
+buffer. With interactive use, this is done by invoking the command with
+a universal prefix argument (=C-u= by default). When called from Lisp,
+the LOCAL argument must be non-nil.
