How would you express "pausing to think" in Japanese?


I was wondering how would you express pausing to think in Japanese. So for
example in English it would be said as "hmmmm...".

I believe あのう。。。 can be used but are there any more ways to do so?

I hope my question is clear.




  * あー
  * うーむ
  * うーん
  * うーんと
  * えー
  * えーっと
  * えーと
  * そのう
  * ふうむ
  * んー

I am sure there are more.
