That is true.
I remember moving from typewriter to mainframe, where I had to get used
to having no deadkey, and having to devise the workaround of using
forward slash '/' for acute, backward slash '\' for grave, etc., AFTER
I got quite used to doing that at high speed on green or black screens
in virtually dark computer rooms, I then had to readjust again when
computers 'advanced' to having dead key characters entered BEFORE the
vowel, which is how it works on all the machines I have now.
