Selecting Delete without Mouse

Hi there,

I have a simple navigation/keyboard question. I know a lot of things these days are switching to be more mobile/touch screen friendly, but I am still someone who would rather navigate their computer with a keyboard if at all possible.

I am wondering is there a way to select "Delete" when deleting a file, without having to click. The window in question is this one:

I can select a number of files with Ctrl+A, then hit the "Delete" key, but in order to click the final "Delete" button I have to reach for my mouse and click "Delete"
I can't navigate to it with an arrow key. If I just press "Enter" it selects "Cancel"

Can anyone help me out with improving my workflow and sparing my wrist some pain?
