First, sorry for double post. This really doesn't fit as an edit to my last post though.
GDocs - I discovered today (on accident, of course) how to 'tab' between sheets in a workbook on the Google Spreadsheet program. Use Ctrl+Shift+PgUp or Ctrl+Shift+PgDn to scroll through them. In Excel, this is without the shift key but in browsers (where GDocs live) that goes between browser tabs! Stumbled upon the GDocs method today and thought I would share (possibly everyone but me already knew this?).
TL;DR - Ctrl+Shift+PgUp or Ctrl+Shift+PgDn to change sheets in a workbook on GDocs Spreadsheet.
(Can the above really be too long to read? Maybe, I suppose.)
