7 " This script defineds functions and key mappings for Tab completion in
8 " searches.

10 " Help:
11 " This script catches the <Tab> character when using the '/' search
12 " command. Pressing Tab will expand the current partial word to the
13 " next matching word starting with the partial word.
14 "
15 " If you want to match a tab, use the '\t' pattern.
