A couple of small requested changes to the dialog box from PR 3012

Sorry for not filing these before the PR was merged.

1. I feel like the default option should be "copy to clipboard", since this feature would often be used to share the design on forums or social media. I think.

2. On my Mac, I cannot use the "return" key to activate the selected option (clipboard vs. save to file), meaning the operation always takes two separate mouse clicks. Would be better if the buttons worked like the usual dialog buttons and supported return activation. I can use the tab key to toggle which option is selected, but it doesn't do anything because I still need to click with the mouse.

Does it make sense to have a default option, given how little the feature would actually be used? It's not like you have to use this action every 10 minutes. It would also add yet another option in the preferences dialog.

I don't believe it requires a preference. Just set the clipboard option as default in the dialog, and make it selectable via keyboard. This is indeed a small tweak and it is not high priority. I'm removing the "beta blocker" tag.
