I have been using Adobe products for Graphic Design and Publishing work for many years, and for most of it my co-workers and I have stuck to paper printouts and pencils for markup. Now that we're all working from home, we're relying on Acrobat and PDF markup tools and I'm so frustrated by how unintuitive this program is, compared with InDesign, which I use on a daily basis. I am used to switching from one tool to another with keystrokes that are deep in muscle memory, and I can use them in one way or another when I open Photoshop. But Acrobat's tools are extremely difficult to use. Why can't I assign keystrokes? Why are there no keystrokes for the tool I use most often ["insert text here"]. If I accidentally hit a particular key it takes me out of commenting to another area entirely and I need to undo everything to get back to commenting. I know I'm not the only person in the publishing world who is really hamstrung by the limitations of this program for working in a Covid world and, frankly, I don't expect us to ever go back to the old paper markup days. Please consider upgrading the program for people who are using it every day!
