This option specifies how keyword completion |ins-completion| works when CTRL-P or CTRL-N are used. It is also used for whole-line completion |i_CTRL-X_CTRL-L|. It indicates the type of completion and the places to scan. It is a comma separated list of flags: . scan the current buffer ('wrapscan' is ignored) w scan buffers from other windows b scan other loaded buffers that are in the buffer list u scan the unloaded buffers that are in the buffer list U scan the buffers that are not in the buffer list k scan the files given with the 'dictionary' option kspell use the currently active spell checking |spell| k{dict} scan the file {dict}. Several "k" flags can be given, patterns are valid too. For example: > :set cpt=k/usr/dict/*,k~/spanish < s scan the files given with the 'thesaurus' option s{tsr} scan the file {tsr}. Several "s" flags can be given, patterns are valid too. i scan current and included files d scan current and included files for defined name or macro |i_CTRL-X_CTRL-D| ] tag completion t same as "]"
