How to reverse Tab and Tab-Shift for keyword completion?

[dpc]

It seems that "keyword" completion is cycling from the bottom to up in my Vim. I was able to fix it with:

diff --git a/autoload/CleverTab.vim b/autoload/CleverTab.vim
index 612bbb0..781761e 100644
--- a/autoload/CleverTab.vim
+++ b/autoload/CleverTab.vim
@@ -54,7 +54,7 @@ function! CleverTab#Complete(type)

   elseif a:type == 'keyword' && !pumvisible() && !g:CleverTab#cursor_moved && !g:CleverTab#stop
     echom "Keyword Complete"
-    let g:CleverTab#next_step_direction="P"
+    let g:CleverTab#next_step_direction="N"
     let g:CleverTab#eat_next=1
     return "\<C-P>"

but do I need to manually alter this plugin to have that behaviour? Is there a reason why default is bottom-up?

I should set that as an option.

The reason why it's like that is the same as
"Why does TAB navigate the completion menu from bottom to top?"
in SuperTab:

Meaning that the usual need is to reuse something recently typed (something that is above current cursor position), starting from the nearest occurrence.

So the bottom completion is actually "the best one"? I don't really care much about which direction it goes, but it's inconsistent between different completion modules. So sometimes it goes up. sometimes down, and it's confusing.
