Hotkey for delete selected node/edge

[keyserj]

Describe your issue

It's nice that we've got a toolbar button and right-click menu option to delete a graph part (node/edge)

but if my hands are on the keyboard, I lose hundreds of milliseconds moving my hands to the mouse in order to click one of those options.

Solution you'd like

If a node or edge is selected, pressing Delete should delete it.

Note: if typing in the node's textbox, delete should do the typical text-editing, not delete the node.

Alternatives you've considered

Technical ideas and questions

Should be very similar to setting the score for the selected node/edge, except:

• instead of doing something with the score, we need to delete the graph part
• we should also only continue with deletion if the user has permission to; should be able to check via the canEdit hook
