change the transparency of all highlights at once

[Leandro24331073ec9j]

Hi!

Is there any way to change the transparency of all highlights at once?
I have files with more than 1,500 highlights and I would like to change just the transparency of all of them at once.

Selecting all and trying to swap with CTRL+E doesn't work.

Thank you

Doing it in Reader is going to be tricky, as it requires using a script. If you had Acrobat it will be much easier, as you could run the code from the JS Console. Reader has this Console, but getting it to open is not as straight-forward as it is in Acrobat...
