The first time I used Chrome on this computer I mistakenly typed in the URL/Search textbox “C/#” instead of “C#” and now eveytime I write a sentence that starts with “C#” it “auto-corrects” it to the C/#, and since it’s the first word in the URL box the browser thinks it’s a protocol name (e.g http://, ftp://, etc…).
I read online that you can select the entry and press SHIFT + DELETE but it won’t work…
How can I remove it?
You didn’t mistakenly type C/#, it’s actually an older bug that resurfaced.
See https://code.google.com/p/chromium/issues/detail?id=409845 (reported Sept 2).
Or here (reported Aug 21st)
Another user had this problem too here.
Chrome developers are already working on it so it should be fixed soon.
