How to add specific autofill entries within Google Chrome?

Similarly to this other question about deleting specific autofill entries from Chrome, I would like to add an autofill entry to an input field on Chrome, so I don’t have to retype it next time.

Deleting one specific entry can be done with Shift+Delete when the entry is selected, is it possible to add the one currently typed in the input field?

Note that it’s not an address, username or password, just a database name I happen to regularly type in a web console. I didn’t figure out how the autofill entries are actually saved.
