Ability to delete multiple rows (or act on multiple items in general)

[brandondrew]

Is your feature request related to a problem? Please describe.

In most apps there is a way to perform an action on multiple items at once, but that does not appear to be the case at least when trying to delete multiple rows of a table. This makes it very tedious to do this:

Describe the solution you'd like

1. Normal keyboard shortcuts should work on multiple items.
2. Selecting commands from menus should not remove the selection, but should instead allow the command to be applied to the entire selection.

As a bonus, it would be helpful if the menu also remembered the last command chosen, so that it could be positioned such that you can choose that command multiple times more easily. (In this case the position of the menu could have put the deletion command near the mouse cursor, making this much smoother.) I can open a separate issue for this more peripheral request, if you'd like.
