Comment 31 for bug 89235

Thanks for the quick reply. Since this has kind of been fixed, and that the PgUp/PgDn keys still do not work (but this may be the default) I have marked it as a Wishlist item. I would suggest to re-enable this functionality permanently to contact the developers of the package directly and see if they would be willing to change the defaults back to how they were, i.e. PgUp/Dn.
Glad to see that you found a workaround, will update the description. Thank you again for helping to make Ubuntu better!
