   - Comma (',') is the tag delimiter in DB. A tag cannot have comma(s) in it. Tags are filtered (for unique tags) and sorted. Tags are stored in lower case and can be replaced, appended or deleted.
   - Page keywords having a word to comma ratio > 3 are appended to description rather than tags.
   - Parent folder (and subfolder) names are converted to all-lowercase tags during bookmarks HTML import.
-  - Releases prior to v2.7 support both capital and lower cases in tags. From v2.7 all tags are stored in lowercase. An undocumented option --\fIfixtags\fR is introduced to modify the older tags. It also fixes another issue where the same tag appears multiple times in the tagset of a record. Run \fBbuku --fixtags\fR once.

The LHS of the operands denotes the indices and ranges of tags to apply (as listed by --tag or key 't' at prompt) and the RHS denotes the actual DB indices and ranges of the bookmarks to apply the change to.
