And if that is patented (like the right swipe) then no other system will
be implementing it. Probably, we can think of something better to
achieve the same goal. And make it portably available to all.

One idea:

A new input-method: accented-cycle (C-u C-\ "accented-cycle" RET).

Once you have this input-method selected, then repeating same key will
cycle through the accented options. Ofcourse sometimes it is useful to
cut off input method so that instead of cycling you just repeat the same
character in the typed text. This is already very well documented in the
"(emacs) 22.3 Input Method".

Also, the newly added "transient" input method will also be added help.

So, why "press and hold" when you can simply "glide".
