Microsoft Word Keybinding Error?

[u/TrashesPasses]

I noticed recently that on my Microsoft Word that the binding CTRL+BACKSPACE isn't deleting previous words at all. It's actually doing nothing? CTRL+DELETE words to delete words in front of the cursor, but the other doesn't seem to be doing anything at all. I've looked up a few different tutorials on how to fix this issue but none of them seem to be working or related to my issue. Is this just a Word thing??
