edt: Scroll margins
7.4 Setting Scroll Margins
==========================
Scroll margins at the top and bottom of the window are now supported.
(The design was copied from ‘tpu-extras.el’.) By default, this feature
is enabled with the top margin set to 10% of the window and the bottom
margin set to 15% of the window. To change these settings, you can
invoke the function ‘edt-set-scroll-margins’ in your ‘.emacs’ file. For
example, the following line
(edt-set-scroll-margins "20%" "25%")
sets the top margin to 20% of the window and the bottom margin to 25% of
the window. To disable this feature, set each margin to 0%. You can
also invoke ‘edt-set-scroll-margins’ interactively while EDT Emulation
is active to change the settings for that session.
*Please note:* Another way to set the scroll margins is to use the
Emacs customization feature to set the following two variables directly:
‘edt-top-scroll-margin’ and ‘edt-bottom-scroll-margin’.
Enter the Emacs ‘customize’ command. First select the ‘Editing’
group and then select the ‘Emulations’ group. Finally, select the ‘Edt’
group and follow the directions.
