Keynotes are defined in a tab-delimited text file. The first portion of the text file is reserved for major headings/categories (the parent values). The remainder of the file is for sub-headings/categories (the child values). A tab-delimited file requires the use of the Tab key to create spaces between data entries.
Changes made to the keynote table are not available in the current project session of Revit. Changes are available when the project is closed and reopened.
You can use Microsoft® Excel or a similar spreadsheet application to manage the data, then export it to a tab-delimited file format.
