Yeah, plenty of other applications key into the common Windows keyboard shortcuts, but developers aren't required to or anything, that just happens to be a good way to please people like me (who live by keyboard shortcuts).

I have a program I use all the time that doesn't use Ctrl+W to close items within the program, opting instead for Ctrl+F4, which is a weird choice because Alt+F4 is the shortcut for closing an entire app (or initiate a Windows shutdown, if you're focused on the desktop or taskbar).

So yes, I really appreciate when developers of Windows programs use the Windows shortcuts. It creates a lot less confusion within the OS.
