If it's lyx or latex documents you can just copy and paste. Lyx will work as is. Latex math you need to either paste into an existing math block or paste as normal text, then select the math parts and press Ctrl-M to create a math block of the text.
If it's openoffice it may be possible to export to latex first and then possibly import it into lyx (don't know how well the math export works). If it's word or pdf you are probably stuck with rewriting the equations -----Original Message----- From: news [mailto:n...@ger.gmane.org] On Behalf Of pol Sent: Saturday, March 28, 2009 21:31 To: lyx-users@lists.lyx.org Subject: collecting items Often i have to pick up math questions from several previously made documents to build up a new one (homework, test, other deliverables).
