A shortcut to close scene

[lchauvin]

Hello,

I was thinking that it would be nice to have a shortcut to close the scene / clear the data, so we can easily open and close data, without reloading Volview or selecting and deleting all data.

Is this is something you would be interested in ?

Thanks.

I would like a keyboard shortcut to delete the current volume. (Also, we might have a memory leak that keeps loaded volumns/files in memory even after deleting...)

and also one to clear all ?

Why not.

To be clear: New keyboard shortcuts/accelerators are great. Adding more buttons I'ed preffer to avoid, and would rather change our current delete buttons, if their not sufficent.

I create a PR with a keyboard shortcut to remove current image, and clear the whole scene:
