I have a spreadsheet in Google Docs that I want to access on my Eris. I want to have a local copy on the Eris because accessing it on Google Docs from the Eris is too slow.

GDocs Help says:

Before you start working with your documents, create local copy by download them to your device.
Call context menu by long pressing on selected document in list
Select "Download" option
Downloading document allows you to edit document
Note: You can download only text documents, for spreadsheets and PDFs use view or export options.

My questions:

1. How do I "export" a spreadsheet so I can have a local copy?

2. If I have a local copy will it stay in sync with changes I make on Google Docs?
