[Message part 1 (text/plain, inline)]

The reproduce steps:

1. Open Emacs with -Q

2. Copy the following code to *scratch*

```
(with-current-buffer (get-buffer-create "*TestBuffer*")
  (let ((inhibit-read-only t))
    (insert (propertize "aaaa"
                        'mouse-face 'highlight
                        'follow-link t
                        'help-echo "mouse-2: some tips"))
    ))
```

3. Put the cursor after the last parenthesis and M-x `eval-last-sexp`

4. M-x `switch-to-buffer` "*TestBuffer*"

5. Put the mouse over "aaaa".

The Expected Behavior: shows "mouse-2: some tips".

The Actual Behavior: shows "mouse-1: some tips".

Emacs 29.3 on Windows 10.

Anyone can reproduce it? Thanks.

Best Regards,
Siyuan Chen

This is not a bug, but the intended behavior.  It is triggered by the
follow-link text property and the default value of
mouse-1-click-follows-link.  If you don't like this behavior, set
mouse-1-click-follows-link to nil.

 I reported this issue because I once wanted to search the Emacs codebase
for a string, such as "mouse-1: some tips" on mouse hover, but couldn't
find it. Later I realized that it was automatically mapped to "mouse-2".
Emacs seems to recognize some keywords (e.g. "mouse-1", "mouse-2") at the
beginning of the string on help-echo.

Anyway, now I know what happened there.

Thanks.

Best regards,
