Implementation Specific Details
Many implementations employ further, multiple-word optimizations. Usually, a commonly used digraph (two character word) in which both characters have short form two-keystroke representations can be combined into a single, four keystroke representation which generates two characters rather than one. There are also a few 3-character shortcuts, and even one rather longer, politically motivated one. Some examples of these are provided in the examples section below.
Another common feature is the use of the 'z' key as a wildcard. The Wubi method was actually designed with this feature in mind; this is why no components are assigned to the z key. Basically, one can type a z when unsure what the component should be, and the input method will help complete it. If one knew, for example, that the character ought to start with "kt", but was unsure what the next component should be, typing "ktz" would produce a list of all characters starting with "kt". In practice though, many input method engines use a tabular lookup method for all table based input systems, including for Wubi. This means that they simply have a large table in memory, associating different characters to their respective representations. The input method then simply becomes a table lookup. In such an implementation, the z key breaks the paradigm and as such is not found in much generalized software (although the Wubi input method commonly found in Chinese Windows implements the feature). For this same reason, the multiple character optimization described in the previous paragraph is also relatively rare.
Some input methods, such as xcin (found on many UNIX-like systems), provide a generic wildcard functionality which can be used in all the table based input systems, including pinyin and virtually anything else. Xcin uses '*' for auto-complete and '?' for just one letter, following the conventions pioneered in UNIX file globbing. Other implementations probably have their own conventions.
See Wubi_86 for details on how to get the Wubi input method installed on Windows.

Famous quotes containing the words specific and/or details:
“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
—Herbert Spencer (1820–1903)
“There was a time when the average reader read a novel simply for the moral he could get out of it, and however naïve that may have been, it was a good deal less naïve than some of the limited objectives he has now. Today novels are considered to be entirely concerned with the social or economic or psychological forces that they will by necessity exhibit, or with those details of daily life that are for the good novelist only means to some deeper end.”
—Flannery O’Connor (1925–1964)
