When importing text into an OpenOffice document, I suggested to a naïve user that she export the LyX document as text. She had two problems, both of which merit attention to LyX's menus, I think.
First, in most programs, "Text" is a file type listed on the save dialog, not under "Export", which tends to be reserved for non-editable formats such as PDF. This is certainly the case in most word processors. Hence, she was confused because there was no option in "Save as" to change the file type to text.
Well, I wouldn't want any document types under "save as". Word processors that offer "save as...document type" tend to fully support working with those document types, and remember to keep using that type for subsequent saves. Lyx works with lyx documents, I don't see any other choices there.
Export means to create a file in a different format for _some other_ software to use. I.e. lyx won't necessarily support the exported file in any way. Which is true for things like pdf.
Secondly, and much easier to fix, she then said "but there's no option to export as text". She didn't know that ASCII means plain text. I suggest the menu entry be changed to say "Plain text" or similar, again, in line with most wordprocessors.
I agree to this, "plain text" is a better word here.
