Left-click causes invoking `widget-button-click' by the mouse-1
event, and `shr-browse-url' by the mouse-2 event 0.6 sec after
(I tested it by adding a logger code to each function). But
middle-click invokes only `widget-button-click' by down-mouse-2.
At the link position, there are two keymaps[1]:
There is an overlay here:
From 876 to 882
button url-link (widget)Top
evaporate t
face nil
follow-link nil
help-echo [Show]
-> "https://www.amazon.co.jp/..."
keymap [Show]
-> (keymap ...(mouse-2 . shr-browse-url) (follow-link . mouse-face)...
mouse-face (highlight)
pointer hand
There are text properties here:
face (variable-pitch shr-link (:foreground "#333333")...
follow-link t
help-echo [Show]
-> "https://www.amazon.co.jp/..."
keymap [Show]
-> (keymap ...(mouse-2 . shr-browse-url) (follow-link . mouse-face)...
local-map nil
mouse-face highlight
shr-url [Show]
-> (the same as the help-echo string)
IIUC, the overlay is what `mm-convert-shr-links' adds, and the
text properties are what `shr-urlify' adds. Though Lars wrote
in 2013-06-17 as follows, is it really necessary?
* mm-decode.el (mm-convert-shr-links): Override the shr local map, so
that Gnus commands work.
[1] I wrote "there are three keymaps" last month but it's wrong,
probably.
