I will guess that you are asking about the Math feature of OpenOffice (File → New → Formula). Sorry, but I don't see a two-sided arrow in the list of formats. If this is a requirement, perhaps other software will better meet your needs. Writer (File → New → Text Document) also provides various overline styles, but none are a two-sided arrow.anjutama wrote:I need to write proofs with line names, which is AB with a two-sided arrow on top.
