Description: Text-based spreadsheet with VI-like keybindings
«Spreadsheet Calculator» is a much modified version of the public-
domain spread sheet sc, which was posted to Usenet several years ago
by Mark Weiser as vc, originally by James Gosling. It is based on
rectangular table much like a financial spreadsheet.
Its keybindings are familiar to users of 'vi', and it has most
features that a pure spreadsheet would, but lacks things like
graphing and saving in foreign formats. It's very stable and quite
easy to use once you've put a little effort into learning it.
