I've googled (or, rather, Duck Duck Goed) and have found lots of lists of Windows 10 shortcuts and one site that listed 12 programs that use CTRL-Shift-R, including HyperSnap. Which is to say, how do I find out which key combinations AREN'T currently being used by anything on my computer? With so many possibilities, trial and error doesn't seem very practical. Can I re-set things so that HyperSnap controls CTRL-Shift-R? If so, how? Is there a way to find out which program currently has usurped that key combination? Though I'm very reluctant to switch to a different key combination after using the same one for many years, I'd like to know how to do that if I have to. I'm wondering how best to deal with this. When I use CTRL-Shift-R, nothing happens.

I use it a lot, and I've used it several times since upgrading to Windows 10. The message also said "They may be in use in another program." The only one I'm concerned about is CTRL-Shift-R, which Hypersnap uses to capture part of a screen. Today, when I started my computer, I saw a message on my screen that said that the following key combinations no longer work: CTRL-Shift-C, H, R, and X. That includes HyperSnap, a wonderful screen capture program that I've used for a zillion years or so. All went well, and amazingly almost all my programs continued to work. A week ago, I upgraded my computer from Windows 7 Pro to Windows 10 Pro.

I'm hoping someone can help me with the following.
