casing for builtin links
The sections corresponding to each builtin should consistently use the casing of the builtin, as this allows direct linking to the relevant help section for a builtin via bookmarklet like: https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#%s (or other similar method to jump to a documentation URL)

NAN
Hi, friends! For the record, OpenSCAD rocks. Brief suggestion: somewhere in the documentation, indicate the meaning of "nan", which is sometimes returned from an "echo" command. Through forum searching, I found that it means "not a number" which, ultimately, was very helpful during my debug.

offset - extrude
The 'offset' chapter (4.10) should be moved to the 'extrusion' (3.7) chapter, it mostly makes sense in this context. --Edoe (discuss • contribs) 08:59, 2 October 2017 (UTC)

hand module
Where is the 'hand' module defined? It is used in the examples for mirror. Thanks.
