Are you talking about the tool buttons at the top and Tiles/Navigation tabs on the left? If so, I don't know of any ways to change those.
You can, however, make the itemID/tile images larger in the view area by changing them in Settings at the top. If you're having trouble clicking the Tool icons, try right clicking in the editor window anywhere and you'll see options for commands as well as F-key shortcuts. Hopefully that helps some.
Another option which seems to work on Win 10 (I just tested) is to go to your Display settings, scroll down to "Change the size of text, apps, and other items" and play with the slider. It affects everything, so you'll need to rest it when not using CED, but it successfully zooms everything.
