Add a "delete-line" action
Depends on !66 (merged), closes #13 (closed).
I chose <Ctrl><Shift>del
as default keybinding, as suggested by @matt in #13 (comment 3723), and consistently with default keybindings of the underlying keybinding signal (del
to delete chars or selection, <Ctrl>del
to delete words).
