No recommendations on a calculator. The one I use doesn't have that functionality, but it does let me copy and paste the tape into Adobe comments/textboxes which is worth the opportunity cost to me.
Just came here to comment on the calculator button. My keyboard has a physical button as well, but it originally defaulted to the native Windows calculator. There is a way to change this, but involves registry key changes. Pretty easy for me to do, but I'd rate it intermediate level in terms of difficulty of doing it.
Here is the guide:
Open Registry Editor and navigate to this location:
HKLM/software/microsoft/windows/currentversion/explorer/appkey/18/ShellExecute
NOTE: HKLM stands for HKEY_Local_Machine
If it ShellExecute does not exist, right click and click "New" and then "String Value". Name it ShellExecute and add the path to your program as the value data.
Hope this helps!
