Absolutely, all behavior can be changed somehow. But the default defines the product :)

Ah the classic Linux community response to any complaint.

1. The default either actively ignores what every other software does or purposely uses something other than everything else for no apparent reason.
2. Someone brings up the fact that it makes no sense why it's different and how it makes the user experience worse.
3. Someone else recommends a half baked solution that still doesn't really solve the problem and doesn't address the fact that the specific weirdness being default is the issue. So it ignores the actual complaint and only provides a half solution.
4. Nothing is ever done to address the issue and it remains for decades constantly annoying new users and being one of thousands of small issues that turn potential curious new users away as they accumulate.

Interesting. And yet it's still incomplete. F6 and Alt+D both do the same thing (focus the address bar), so there's at least one line missing and definitely at least one column.
