Part of the goal of this website has been to make Chinese characters easy to lookup. To that end, using cangjie input codes was a nice means of organizing Chinese characters since not only did if provide a means for grouping characters alphabetically by shape, it also offered a way of inputting them, based on their shape.
In the process of working on an ebook dictionary, a simpler means of looking up Chinese characters was developed. It's called the Easy Lookup system.
The Easy Lookup System is based on 12 Easy Lookup Keys.
It's used in the Chinsym Chinese character dictionary as the main means of looking up Chinese characters.
As an example of how this system works, Chinese symbols whose cangjie code begins with c/金 have these shapes at the top: 金丷八.
These elements, two horizontally opposed strokes angling down and out or down and in are grouped under the hat 八 Easy Lookup Key.
The hat Easy Lookup Key includes characters that begin (or are surrounded by) the elements below, which are called Key Derivatives or Derivatives:
The Derivatives for this Easy Input Key have variations and the variations are how characters are grouped in each of the Easy Lookup Indexes.
Here are some of the derivatives for the Hat Key listed vertically with their variations included after a dash (if their are variations).
