After starting emacs -Q evaluate the following:


(defun test-me ()
(interactive)
(message "Test Me: %s" (key-description (this-single-command-keys))))

(defun test-me-2 ()
(interactive)
(message "Test Me 2: %s" (key-description (this-single-command-keys)))
(call-interactively 'test-me nil (read-kbd-macro "C-1" t)))


(global-set-key (read-kbd-macro "C-c a" t) 'test-me-2)

Then, Type C-c a. The message shows:

Test Me 2: C-c a
Test Me: C-c a

It should show

Test Me 2: C-1
Test Me: C-c a

At least thats how I understand the call-interactevly documentation:

This function calls the interactively callable function command, providing
arguments according to its interactive calling specifications. It returns
whatever command returns.

If, for instance, you have a function with the following signature:

(defun foo (begin end)
(interactive "r")
...)
then saying

(call-interactively 'foo)
will call foo with the region (point and mark) as the arguments.

An error is signaled if command is not a function or if it cannot be called
interactively (i.e., is not a command). Note that keyboard macros (strings
and vectors) are not accepted, even though they are considered commands,
because they are not functions. If command is a symbol, then
call-interactively uses its function definition.

If record-flag is non-nil, then this command and its arguments are
unconditionally added to the list command-history. Otherwise, the command
is added only if it uses the minibuffer to read an argument. See Command
History.

The argument keys, if given, should be a vector which specifies the
sequence of events to supply if the command inquires which events were used
to invoke it. If keys is omitted or nil, the default is the return value of
this-command-keys-vector. See Definition of this-command-keys-vector.
