i've got a big doc with lots of headings assigned
i'd like to select a load of text, and change all heading1 to heading2, all heading2 to heading3, etc. so that the relationships stay the same they're all just one higher (or lower)
eg before:
*HEADING 1
some text
*Heading 2
more text
after:
*Heading 1
*Heading 2
some text
*Heading3
more text
basically i want to add a new category 'above' the existing text
is anything like this possible?
