How to remove an entry from Chrome's Remembered URLs from the url bar?

Follow the steps below to remove individual items from the address bar's remembered URLs:

1. Type local.mysite.com
2. Use the ↑ ↓ keys to move focus to the item you wish to delete
3. Press the relevant keys depending on which OS you are using:

Windows and Linux:

• Press Shift + Del

macOS:

• Press Shift + Del (when the keyboard has a dedicated Del key)
• Press Fn + Shift + Backspace (otherwise)

Note: this will only work for items that have the paper icon () next to them.

In older versions of Chrome this is a globe icon () instead.

Another option is to browse the history tab of Chrome (chrome://history) and click the menu next to the URL you want to delete.

Below is a screenshot - sorry it is in German, but you should get the idea. In the German menu it is the second option (Aus Verlauf entfernen).

In Chrome v86 (maybe earlier too) on my MacOS when I type in the URL bar and move the mouse cursor over a suggestion, an X button appears with the tooltip "Remove suggestion". After clicking this X, the chosen suggestion no longer appears.

A recent version of Chrome changed how to remove entries from the auto-complete list: you should now use the X button on the (far) right of the URL, in the auto-completion list.
That button will only appear for the first suggestion, but will also appear for other suggestions if you hover over them.
