Kile supports user defined lists of abbreviations, which are replaced
on demand by longer text strings. Look at
->->+Complete
to configure one or more of theses lists. For the example given here, the
abbreviation list in example.cwl must be chosen.
In this file you will find for example the entry L=\LaTeX for example.
For example, type only the letter L. Now invoke
the abbreviation mode of word completion with
->-> or keyboard shortcut Ctrl-Alt-Space,
and the letter L is replaced by the string
\LaTeX.
