Change Specific Fonts And Sizes

This is what I have:

set the font of (every word where it’s font is “Lucida Grande” and it’s size is 33) to “Gill Sans”

This is what I want:

A script to change the font and fontsize of a specific font with a specific fontsize

Example:
Change Lucida Grande 33 → Gill Sans 15

I tried to continue the script above with …“and set the size to 15”… but of course it didn’t work!

Are there more text attributes you can manipulate with Applescript such as Style, Aligning, Color
And how can you manipulate them?

Is there no way to do that? :?: :cry:
