Allow the 'Select all' tool to select all the content of all pages at once
I've never used a program that can edit documents that doesn't let the user select all content of all pages in the document at once, yet that is how Adobe Acrobat works. it seems impossible to select all the content of a PDF to do something as simple as say change the font size/color etc.
Please please add this as an additional option, either by making a second repeat of the command select across all pages or making the command work with a different key combination.
I still can't quite believe I'm writing this request... surely I have it wrong and this is possible, yet it seems that it isn't.
