A simple question on copy/paste

[Stephen Liu <satimis yahoo com>]

Hi folks,

What will be the simple way to copy and paste selected text/paragraph
from .ps/.pdf file on text editor?

Occasionally I printed technical documents on Internet as .ps file. 
However I was unable to copy/paste their content on .txt file without
going through a long way, treating them as graphic file.  Conversion
.ps -> .pdf -> .html was not alway working perfectively without error. 
The version of Acroread (Acrobat Reader) running on this box does not
have text-selecting function.  Saving technical documents on Internet
is sometimes prohibitted.

Please shed me some light.  TIA
