I have been carrying around a copy of the Windows XP calculator ever since Microsoft decided that nobody can do both decimal values and decimal <-> hex <-> binary conversion without having to go through a menu to change modes. With the XP calculator, I use F5-F8 as shortcut keys for changing bases whenever I want. The Windows 10 calculator doesn't even do anything with those keys in scientific mode.
