Re: [ jEdit-users ] Horizontal scroll lock

[Steve C. <sjc...@gm...>]

Wow.  That was quick, and quite affective.  I work with java, but haven't
done any jEdit bean shell scripting.  I'll try to use this as a launch
point to write a macro that doesn't ignore the scroll bar/cursor events,
but ignores events that cause the automatic jump to the left.  This lock is
a little too affective.  You should call it "Horizontal vice grip".  lol

Thanks for the script,
Steve
