C -- Command name: symbol with interactive function definition.
d -- Value of point as number. Does not do I/O.
D -- Directory name.
-e -- Parametrized event (i.e., one that's a list) that invoked this command.
+e -- Parameterized event (i.e., one that's a list) that invoked this command.
If used more than once, the Nth `e' returns the Nth parameterized event.
This skips events that are integers or symbols.
f -- Existing file name.
s -- Any string. Does not inherit the current input method.
S -- Any symbol.
U -- Mouse up event discarded by a previous k or K argument.
-v -- Variable name: symbol that is user-variable-p.
+v -- Variable name: symbol that is `custom-variable-p'.
x -- Lisp expression read but not evaluated.
X -- Lisp expression read and evaluated.
z -- Coding system.
In addition, if the string begins with `*', an error is signaled if
the buffer is read-only.
-If the string begins with `@', Emacs searches the key sequence which
- invoked the command for its first mouse click (or any other event
- which specifies a window).
+If `@' appears at the beginning of the string, and if the key sequence
+ used to invoke the command includes any mouse events, then the window
+ associated with the first of those events is selected before the
+ command is run.
If the string begins with `^' and `shift-select-mode' is non-nil,
Emacs first calls the function `handle-shift-selection'.
You may use `@', `*', and `^' together. They are processed in the
