Any way to disable auto select?

I find that frequently when a new item gets added to my hotbar, it auto selects it. I find this frustrating because usually I have something like my hoe selected. Then I pick some corn, and suddenly it's selected. Then I accidentally try to eat the corn. Or I buy some seeds and then try to talk to someone next to the counter and I give them my seeds. I didn't want to do that!

Edit: After paying closer attention, it may only happen when I have nothing selected and then get something. I guess I should make better care to move my selection back to my tools.

Is there some way to keep the cursor from changing positions just because you picked up a new item?
