+=head1 CUI
+
+The character based user interface is organized as a spreadsheet. Each
+row resembles an event and every data field has a column. Due to screen
+size limitations it is unlikely that all columns are visible at one
+time.
+
+Column headings at the top show the name of each data field. Column
+headings stay at the top of the screen and don't scroll off.
+
+Row headings on the left show status information about the entry encoded
+into a single character. Row headings stay on the left side of the
+screen and don't scroll off.

+ " " event is in good shape
+ "R" event was just read in and no status was ever computed (never shown)
+ "E" event has one or more errors
+ "M" event was modified outside CUI (crc32 fails)
+ "N" event is new
+ "Y" event is in yank buffer
+ "y" one data field of this event is in yank buffer
+ "D" event has been deleted (never shown)
+ "U" event was deleted and deletion was "undo"ed

+
+The navigation and operation is loosely based on vi(1) concepts and
+keystrokes. There are two modes of operation, cursor movement and data
+cell editing. The CUI starts in cursor movement mode which can be
+identified by the active cell being displayed reverse. Some keybindings
+enter data cell editing mode which can be identified by the active cell
+being displayed normal with the cursor prominently visible.
