To change the names of the Master Comment or Comment column headings:
1 Control-click a Comment column heading, then choose Edit Heading from the
shortcut menu.
2 Type a new name in the column’s Name field, then press Return.
The Master Comment and Comment column headings are the only column headings
you can change. Once you customize the name of a Comment column, it remains
changed in that project file, even if you hide it. New projects you create use the
default names.
If you want to change several Comment headings at once, use the Project Properties
window. For more information, see Volume II, Chapter 5, “Working With Projects, Clips,
and Sequences.”
Control-click a Comment
column heading, then
choose Edit Heading.
Enter the new
column name.
