FCKeditor in Popup fullscreen

Hi my problem is that i need a solution where the fckeditor will be openend in popup with a text which the user inserts before.

i have 2 pages

first page (the original editor in oracle portal):
there is an inline frame where the fckeditor is working inside. this frame can't be changed in any way and its not very big. so i decided to make another button in fckeditor to open the text in fullsize.

second page (a self programmed html page where the editor is also called):
this second page is openend in popup with the editor and i would like to get the text out of the first editor.

My questions:
- is it possible to give the textinput to the popuppage und after editing the text back to the original page?
- in which file do i have to make changes to add another button near the fullscreen button?

perhaps anyone has same problems and could help me.
iam using fckeditor in version 2.6.1 in oracle portal 10g.
