Please give me some help with swapping identically sized ranges.

I have several ranges and what I would like to do is
have one button assigned to each range .
Here is how this would work
There is a variable which is normally set to zero.
I press a button the first cell in its range changes text color t
indicate
that the button press has been registered and the variable is changed.
The color change and variable value have a time out.

If a second button isnt press before the timout the variable goes bac
to zero
and the cell text is returned.

If a second button is pressed before the time out the a swap take
place.
The variable is used by the sub to determine which range was chosen
by the first button press.

Note: the sub distinguishes between a 1st press and a 2nd press by
the variable... a zero determines that it is a 1st button press.
Each button calls the sub with a different variable

some of the questions I have are
what is the basic structure code to swap 2 same sized ranges?
how do I write code that holds conditions true for only set amount o
time?
where would I Dim my variable? It needs to reside outside the sub.

any help is greatly appreciate
