+The value of mouse-wheel-scroll-amount means the following:
+
+- By default scroll by one line.
+- Hold down Shift to do so by five lines.
+- Hold down Meta to scroll half a screen.
+- Hold down Control to adjust the size of the text. This is added in Emacs 27.
+
+By enabling mouse-drag-copy-region we automatically place the mouse selection to the kill
+ring. This is the same behaviour as terminal emulators that place the selection to the
+clipboard (or the primary selection).
+
+The other options in short:
+
+- Hide mouse pointer while typing.
+- Enable mouse scroll.
+- Faster wheel movement means faster scroll.
