I often press esc expecting it to dismiss popups etc. (for example, the suggestion popup when typing in a new post title on this forum). As a programmer, I have a very strong reflex to press esc.

That key always exits fullscreen. I do not want that to happen.

Additionally, this behavior seems to override the keyboard shortcuts settings. For example, esc is bound to Stop by default. But if you are loading a page in full screen, esc will exit full screen rather than stop the load.

Also, there are other reports that this behavior interferes with websites that use the esc key.

Therefore, it seems that the behavior of esc is special cased at a low level. So presumably the only way to change this behavior is to file a feature request to the devs.

I think I can answer my own question.

The Local State file in the profile directory has a field called country. I was able to change which settings were shown by changing the country.

I have no idea how this was initially set--presumably one of the options you mentioned.

In settings, I see "Opera offers promotional content in some browser locations".

How does Opera determine this "browser location"?

Is it based on the build? That is, should I download a different binary if I move to a different country?

Is it determined at runtime? Is it just using the location services of the OS?
