action macro - how to select last layout tab

Scripts are not my strongest skill, so I hope to find some basic help.

I want to make a action macro that selects the copy the last layout tab, copy that, goes modelspace and -pan @some numbers, go back in modelspace. stop.

I've recorded the following steps succesfully:

Layout

copy

and

mspace

-pan

(basepoint plus some mumbers)

(@-3000,0)

I would like to know the command for selecting the last layout tab. Without using right-click functions which, as I know of, are not recorded?

Hope someone can help

This is the code for getting a list of layout tabs not sure if last is first

(setq doc (vla-get-activedocument (vlax-get-acad-object)))
(vlax-for lay (vla-get-Layouts doc)
 (setq plotabs (cons (vla-get-name lay) plotabs))
)

(setq lasttab (nth 1 plotabs )) ;or (cadr plotabs)

Tank you, Bigal !

I got a bit lost with the code, but I found another lo-fi time consuming practical way :-)

Alternatively:

(car (reverse (layoutlist)))
