+  In addition to the above textual formats,<TeXmacs> documents can be exported in a wysiwyg (what-you-see-is-what-you-get) way to either Postscript or Pdf, which are used as the primary formats for printing documents. <TeXmacs> can also export document fragments to several vector or raster image formats.
+
+  <TeXmacs> documents can be converted to other formats using the different items in the File\<rightarrow\>Export menu. Similarly, the File\<rightarrow\>Import menu contains all formats which can be imported into <TeXmacs>. Besides exporting or importing entire documents, it is also possible to copy and paste document fragments in various formats using Edit\<rightarrow\>Copy to and Edit\<rightarrow\>Paste from. The default formats for copy and pasting can be specified in Tools\<rightarrow\>Miscellaneous\<rightarrow\>Export selections as and Tools\<rightarrow\>Miscellaneous\<rightarrow\>Import selections as.
