When a tool is selected the selection is persistent until the user puts a different tool in focus.
I use the Hand tool. Add it the the Tool bar.
Right click on the tool bar. In the menu that appears, place the mouse pointer over "Select & Zoom".
Another menu appears. Click on "Hand Tool". The tool wil now appear on the Tool Bar. "Select Tool" is also useful.
Single-key accelerators can be used to access tools.
Select Edit > Preferences > Category "General" > tick "Use single-key accelerators to access tools".
On the keyboard the "H" key will fetch the Hand Tool.
I also believe that it is done through the hand tool
