how can we zoom in the column area? when i hit zoom or use the + - buttons at the bottom right corner, it is zooming in the bar area.

sometimes it is hard to read the text at the column area. but i dont want to make them bigger by increasing the fonts, this affects my print area negatively. i just want to zoom in the columns area as it is, so that we can see it better. how to do this? i had not seen it in MS Project 2007. Now I got my MS Project 2010, I still dont see this feature
