I don't use those buttons at all. I tend to use the sliders in the parameters box on the lower right hand side. I can either slide the faders or double click on the fader to bring up the edit dial menu and change the parameters there. I found out early on that using the editing tools didn't work very well with me. And I can get a character posed or put an object where I want to in the scene 100 times faster and without the frustration.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
