Hello!
I'm glad that the extension was helpful in some way - let me try to debug this. Thank you very much for the report!
I'd like to first take a look at what the extension reports as your keyboard shortcuts.
1. Could you paste this URL into a new tab in your browser: chrome-extension://mhdmaokphjlbobmlioagngakkofbchdo/options.html, then,
2. Take a screenshot (or copy and paste) the content in the "Current Features and Keyboard Shortcuts" section. For example, mine looks like this:
3. Similarly, the content of chrome://extensions/shortcuts under the "TurboAnimator" section
While this isn't likely to be the issue, I just want to confirm first that there is no overlap across the reported keyboard shortcuts at the moment.
Also, the issue might be Mac-specific as I've only consistently tested on my combination of Chrome + Ubuntu. In parallel, I'll check the behavior on a Mac.
