I've seen many posts with the shortcut tag that are actually about Shortcuts, not keyboard shortcuts. Many keyboardless iOS questions have this tag too.
I've fallen victim to the same mistake too; while writing a question about Shortcuts, I've tagged it with shortcut. My instinct is to tag such questions shortcuts, but since it doesn't exist the next best option seems to be shortcut (if you're not yet familiar with all the tag names on the site).
I have successfully used the shortcuts-app tag before, only after being told that shortcuts isn't a tag. But I had to hunt for the shortcuts-app tag, because shortcuts-app is not the suggested replacement for shortcuts - the site actually suggests shortcut instead!
No wonder there are so many misattributed tags on Shortcuts posts, the current names are confusing and counterintuitive. I didn't find shortcuts-app to be an easy or obvious tag to discover.
I'd suggest that shortcut be renamed to keyboard-shortcut, and shortcuts should be made a synonym of shortcuts-app.
