Click on "Fetch" and pressing ENTER should accept the Dialog

When you click on "Fetch", a modal dialog appears.
My expectation as a user, is that the focus now should be in the "OK" button.
So that pressing ENTER key should accept the dialog and finish the "fetch" operation.

This is important because doing these repetitive tasks in many repositories everyday would save time and effort, and some users have the ENTER key assigned in one of the mouse side buttons for these type of things, and also for accessibility purposes.

Also if pressing TAB and ENTER when the Fetch dialog appears, should move the focus to the "Cancel" button, so that it gets cancelled instead.

Pressing TAB multiple times should cycle through the modal dialog options, so pressing TAB 3 times should move the focus from OK to Cancel to OK again.

At the moment in the current SourceTree for Windows v3.4.17
if I click on "Fetch" and press ENTER, it is minimizing the whole window since the focused button seems to be the window's minimize button somehow, and pressing TAB only cycles through the buttons in the background, and it is unable to focus on the modal dialog without using the mouse.
