"Use the scrollbar to see the rest of the agreement"
Marketing department of my company suggested to change MUI_INNERTEXT_LICENSE_TOP
from "Press Page Down to see the rest of the agreement"
to "Use the scrollbar to see the rest of the agreement"

(as well as translations in other languages)

I made a fix in my script, but I consider it a good idea to change this in NSIS mainstream as well.

Many people are unaware about a "Page Down" key on their keyboard (especially as the key caption gets often replaced by a picture), but they do know what a scrollbar is...
