New Adobe Acrobat Pro user. How do I get a tutorial about general operation Of Adobe acrobat pro rather than just building a business brand. Program totally ignored the interests I indicated. I do not hold a small business. All I can get his help in creating a brand for a small business. I indicated absolutely no interest in business. I’m a retired scientist trying to move away from using Foxit. I need help in understanding tools that the program provides that there is no tutorial about that. I need help understanding what the different icons mean as regards tools. No tutorial about that. No introduction.
