90+ % of my time is using the hand tool and comment and markup tools to annotate documents prepared by others. Since upgrading from Standard 9.1.2 to 9.4 and 9.4.5, whenever I finish using a markup tool, Acrobat defaults to the text selection tool (which I rarely use) instead of back to the hand tool. This is a huge inconvenience. Is there a fix to keep the hand tool as the default? Thanks.
Something that may help - Preferences > General Category > tick "Use single-key accelerators to access tools".
At completion of some activity press the "H" key to select the Hand Tool.
Be well...
