I have emailed with the developers. And he told me that he would correct the problem. So I supposed it will be in their next release. Since I don't think it would be reasonable to ask for a package update just to fix this I'm going to consider this bug fixed and close it.
I extend the thanks of one of the developers: "Thanks. I wouldn't have noticed the typo myself. I rarely read the docs ;)" Timo Hirvonen -- man page has incorrect bindings for win-top and win-bottom https://launchpad.net/bugs/64525 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
