I'll bite. I'll try to explain why the text below is confusing
to me. So, the section starts of by saying mouse commands use the
primary selection, all others use the clipboard. This is clear.
The X windows application I am using as an example, xterm, sets
and pastes from the primary selection. So my assumption was that the
behaviour I want can thus be achieved by making everything just use the
primary selection; this way when I select using the mouse in an xterm,
which copies it to the primary selection, and then hit C-y, it will
yank the primary selection. This was the old behaviour.
Reading further, I can see that the new behaviour makes the
Commands that kill text or copy it to the kill-ring (M-w, C-w, C-k,
etc.) also put the killed text into the clipboard (apart from the kill
ring). There is no way described to make them go back to just using the
primary selection. Indeed, the last paragraph states that setting
`mouse-drag-copy-region' and `x-select-enable-primary' would make the
mouse use the clipboard -- not what I want.
However, the actual behaviour is different. With:
mouse-drag-copy-region t
select-active-regions nil
x-select-enable-clipboard t
x-select-enable-primary t
|------------------------+---------+------|
| action | Primary | clip |
|------------------------+---------+------|
| Use M-w | Set | Set |
| mouse drag in Emacs | Set | Set |
| mouse-save-then-kill | Set | Set |
|------------------------+---------+------|
| Mouse drag in Xterm | Set | |
| left click/right click | Set | |
|------------------------+---------+------|
Flipping x-select-enable-clipboard to nil,
|------------------------+---------+------|
| action | Primary | clip |
|------------------------+---------+------|
| Use M-w | Set | |
| mouse drag in Emacs | Set | |
| mouse-save-then-kill | Set | |
|------------------------+---------+------|
| Mouse drag in Xterm | Set | |
| left click/right click | Set | |
|------------------------+---------+------|
So the way to have everything just use the Primary selection
(*NOT* the clipboard, one needs just set:
(setq
mouse-drag-copy-region t
select-active-regions nil
x-select-enable-clipboard nil
x-select-enable-primary t
)
If the following bit was clarified:
--8<---------------cut here---------------start------------->8---
**** `select-active-regions' now defaults to t.
It also accepts a new value, `only', which means to only set the
primary selection for temporarily active regions (usually made by
mouse-dragging or shift-selection).
--8<---------------cut here---------------end--------------->8---
Does it mean:
a) temporarily active regions will only set primary selection (and not
the clipboard), or
b) the primary selection is only set by temporarily active regions, and
never else?
In either case, this does not match my experience: even with
select-active-regions nil the primary selection is being set (perhaps
due to x-select-enable-primary and mouse-drag-copy-region set to t)
Also, the final paragraph needs to be corrected:
--8<---------------cut here---------------start------------->8---
*** To return to the previous behavior, where mouse commands use the
clipboard, change `mouse-drag-copy-region' and (on X only)
`x-select-enable-primary' to t.
--8<---------------cut here---------------end--------------->8---

Wow, I'm being shot at from both sides. That means I *must* be right.
