But I don't want my ‘next field’ key to suddently stop moving between fields and instead enter characters, just because some fields of text are different from other fields of text.

The mess goes back to IBM pre-computer unit record (punch card) equipment, for which fields were just columns on a card and moving to the next tab stop was the same as moving to the next field if you set up your keypunch appropriately.

Two hands to delete a character? No, thanks. Not to mention that your consistency argument is out the window because Apple doesn't put Fn in the same place on all its keyboards.

Also, that combo isn't marked on the keyboards, so it may as well not exist for the vast majority of people.

With the demise of the Eject key, there is no excuse for the lack of Delete on Apple laptops. Not to mention that Apple put a hardware delay on the Eject key for some reason, so you couldn't even remap it to be Delete. If accidental CD ejections were causing enough fatalities to demand a NON-DEFEATABLE DELAY, why didn't Apple simply make Eject a secondary function on a Delete key, requiring Fn (and being marked as such)? Both problems solved.
