Draft: Implement "Delete until end of line" action (but don't bind it)
This action deletes until the end of line like Ctrl-k in, say, the System Settings search field. It does not care about current selections and is just for a slight speedup compared to Shift-End Delete, and, more accurately, for consistency with other Qt applications like Dolphin or System Settings.
Ctrl-k was previously taken up by "Insert term translation #2". As
Ctrl-, and Ctrl-. are still not taken, shift #2 onward to Ctrl-p,
Ctrl-n and so on, then use Ctrl-, for #9 and Ctrl-. for #10.
This action deletes until the end of line, but isn't bound by default as Ctrl-k is already taken by "Insert term translation #2".
(#10 previously had a broken default binding.)
I've set this to be a draft as for some reason I can't get the action to show up in the Edit menu...
