I use the address bar in Chrome to type in search engine queries.

Somehow at some stage, I have mistyped C# as C/#. This makes the browser think I am trying to enter an address on the C drive if think and ends up with a not found page.

So half the time while typing c# it automatically reverts during typing to c# even without typing the forward slash. I can see the c# in my addressbar autocomplete list. How can I remove the item? I dont want to clear my whole history.

I have tried the very popular superuser answers for using the cursor down key to highlight and either delete key or shift+delete key to remove the entry. it is not removing that entry or any other I test that method on. So I am wondering if my Chrome v37 does not support that remove method.

How can I remove c/#?!

  • About Shift+Del not working, I didn't noticed the autocompleted result I was attempting to delete was bookmarked -__- Yes I feel silly, I didn't noticed the star icon! (A corporate website changed it's IP and I wanted to delete the old IP from results) Verify if this applies to you.

I don't think you mistyped c#, I think this was a bug that was introduced recently. As I also just started getting this behaviour.

See https://code.google.com/p/chromium/issues/detail?id=406029

I'm guessing that as #'s are used in url's more often now, chrome decides that anything with a # behind it should be considered a web address. For example if you type: "wdqwuuw#" it will auto-correct to "wdqwuuw/#", which you of course don't want.

  • Wow, you figured it out. I will report the bug

  • It's actually an older bug that apparenlty recently resurfaced. This is the new tracker: code.google.com/p/chromium/issues/detail?id=409845 I don't think there is any need to report a new bug, they're on it.

Highlighting the entry+pressing Delete should work, but anyway an alternative would be to selectively delete the history instead:

  1. Type chrome:history into the address bar.

  2. Search for C/# in the search bar(top right corner).

  3. Check all C/# entries and click Remove selected items.

  4. Confirm removing items.

So next time you type C into the address bar you would get C#!


I'm also using Chrome v37 (latest) and the method in your answer works for me?

  1. I type C/ so that the incorrect one(C/#) shows up.

  2. I move my mouse over the autocomplete so it is highlighted as in your picture.

  3. I press Del- it gets deleted!

I can't think of any reason why it doesn't work for you though. Sorry I can't be of more help :(

  • When searching history, it does not return any entries for c/#. I even went to the next (older) page of results.

To clear the Omnibox from entries for which Shift+Delete doesn't seem to have an effect, I pieced together a way to do it. There is a db file that Chrome uses to store the Omnibox entries, called "History". Using a db editor, you can delete entries from this, restart Chrome, and voila! Works for me running Chrome on Windows 7, but the basic idea should work on MacOS and Linux, if necessary.
