 If RamWorks-style memory expansion is available, `EDIT.SYSTEM` can use it as additional editor buffers.  For each 64KB bank of RamWorks expansion, an additional 46KB buffer will be allocated.  With an 8MB RamWorks card, 128 buffers are available.  `EDIT.SYSTEM` is able to support editing of large files (>46KB) by splitting them across more than one buffer.
 
+The help screens are accessed using `Open Apple`-`?` and summarize all the keyboard bindings.
