haha .. if u talking abt da alt + e + .. stuff well it is the shortcut on excel .. basically ALT E S gets you paste special box .. u cn type E for transpose and V for values .. will give u da result ..
plzz forgive me for using short writings/grammar/errors of ny sort etc .. :)
paste link // umm nt sureif m getting it right .. bt u cn surely paste nd transpose simultaneously .. ALT + E + S + E + V .. basically it will get u paste special nd den do transpose + paste value together ..
use VBA .. make a sheet event which gets triggered on change event .. make E1 as target cell and set an if condition which says if its value id S then perform the task ..
create a function .. would be of the following sort ..
concatenate_new(array,delimiter) .. you can pass the array that has to be worked on plus the delimiter which separates them ..
