[IPython-User] hsplit or vsplit?

[Klonuo Umom]

When paging in qtconsole is set to hsplit it renders like this:

| Console | Pager |

and when set to vsplit, like this:

----
Console
----
Pager
----

I don't understand whats horizontal in hsplit (it has vertical
splitter so it splits screen vertically) and what's vertical in
vsplit? If I try harder I may notice that it may mean split in
horizontal columns and vertical rows, but seems strange. It could be
just in my mind or minor syntactic issue
