So you're typing along in Google Docs and you press Ctrl+B to make something boldface, or you press Ctrl+F to open Chrome's text search box, but instead, the AdBlock menu opens! Somehow one of Chrome's standard keyboard shortcuts has been reassigned to open the AdBlock menu. We're not sure how this happens, but it's very easy to fix.
To remove a keyboard shortcut in Chrome:
1. Open chrome://extensions.
2. Click the "hamburger menu."
3. Select Keyboard shortcuts.
4. To remove the shortcut, click the "x" at the edge of the box.
