Code prediction

Hellou, I have a question:

Example: I want to write CSS property "padding-top".

1) I write "pad" 
2) first push Ctrl + Space shows the prediction code
(http://www.imghosting.cz/images/43pad1.png) 
3) I repeatedly push the Ctrl + Space to complete word "padding", but
still nothing

The word "padding" is the only way to continue or not ? So why do I
have to use the down arrow to mark the word "padding-top" and then
"Enter" (complicated) ?

My idea:

1) I write "pad"
2) first Ctrl + Space - shows the prediction code
3) second Ctrl + Space => "padding" (because the word "padding" is the
only way to continue)
4) I write "-t"
5) shows the prediction code with the only option "padding-top"

It is much easier and faster.
