You can get WordSmith to use tags to select one section of a text and ignore the rest. This is "selecting within texts". You can also select between texts: that is, get WordSmith to look within the start of each text to see whether it meets certain criteria.
These functions are available from Main Settings | Advanced | Tags | Only If Containing or Only Part of File.
Defaults
The defaults are: select all sections of all texts selected in Choose Texts but cut out all angle-bracketed tags.
