-** Expanding to the common candidate prefix with TAB
-
-If you leave the default configuration of the completion styles, such that the
-~basic~ completion style is still present, then pressing ~M-TAB~ (~corfu-expand~) will
-expand the current input to the common prefix of all completion candidates. In
-contrast, ~TAB~ (~corfu-complete~) behaves differently and expands input to the
-currently selected candidate.
-
-If you use the ~orderless~ completion style, then expansion works differently by
-default. Orderless only expands to single matching candidates, since due to its
-multi-component input, there does not necessarily exist an expansion to a common
-candidate prefix. However it is possible to define a separate ~tab~ completion
-style. The ~tab~ completion style will only take over ~TAB~ completion (if prefix
-expansion is possible), but besides that won't affect Orderless candidate
-filtering.
