standard keybindings would be a perfectly acceptable solution. better in
fact. my proposal only applied when apps, for some reason or other,
cannot use standard keybindings or menus. Pretending such apps don't
exist is counterproductive, my only concern is interoperability, i.e.

it shall be possible to transfer text from any app to any app via
selections.

this does address the issue and is a very good solution. my proposal
included this as a solution in fact. There was an exclusive or, if you
have an explicit copy/paste then nothing changes. (except to make sure
you are setting PRIMARY as well as CLIPBOARD on copy, but everything
does this anyway) If you have an app without explicit copy then you must
add it. or LESS PREFERENTIALLY do something else, but only if you have
very very good reason. I can understand that you feel that there is a
never a good reason not to add an explicit copy, but the universe of X
applications is large, and my primary concern is making sure that it is
interoperable with each other meaning that we must tell people that if
they wish their app to be able to cut-paste with other apps AT ALL, they
must provide a mechanism for copying to CLIPBOARD.

just saying PRIMARY is an easter egg doesn't work if there are apps
where it is the ONLY mechanism for selection/pasting. this is what I am
trying to fix. so that we MAY tell people it is an alternate method
which is never necisary.
