I can't bookmark search results because it's a result of form submission.

Here's the actual scenario: I'm waiting a package sent by Royal Mail, tracking number RU098755913GB

Go to https://www.royalmail.com/track-your-item Enter tracking number RU098755913GB Bookmark search results Try to restore results by clicking your newly created bookmark - clear form is shown, where I need to enter my tracking number again - no speed gain at all.

As far as I understand, that's because bookmark saves only page URL which does not contain my tracking number, because number was sent with form POST data

Here's how I do it:

Right click on tracking number entering field and select "create search engine" Assign some shortcut for it, let's say "rm" Create a new bookmark and manually modify it's address to "rm RU098755913GB"

If clicking the bookmark would work the same way as if I entered "rm RU098755913GB" into Opera url address field, then I would see my search results - exactly the thing I want.

However bookmark address is formatted as url upon saving and bookmark address becomes rm%20RU098755913GB which is an URL pointing nowhere. I have to manually modify it and replace %20 with a space to get to my results.

Is there a possiblity to make a bookmark which upon clicking would work the same way as if I typed "rm RU098755913GB" into the Opera address field? Like some kind of typing macros. It would really help me / speed up tracking.
