This is again a tiny but handy feature in VS 2010.
I am sure you have ever experienced quite frustrating situation when dealing with inappropriate font size of your code, especially when delivering the presentation with projector. You will need a bigger font so that your audience could see it very clearly.
What we’ve done in the previous version is Visual Studio is to adjust the font size by doing the following action.
From Menu, select Tools –> Options.
When the Options dialog box comes out, select Environment –> Fonts and Colors –> and adjust the Size
It is however could not directly display the whole codes in the resolution which potentially cause readjusting action again.
All of these limitation could be somehow a troublesome and plumbing experience causing the productivity of a developer.
Luckily VS 2010 comes out with an interesting feature that allows developer to adjust the zoom level on the spot, just like what we have in Microsoft Word 
.
If you see the yellow-highlighted part above, it indicates that the zoom level of your editor.
You could know change the zoom level by simple click the desired zoom level on it.
Alternately, you could also use short cut key ( Ctrl + mouse scroll ) to increase your productivity and convenience as appropriate.
