Is there a way to set separate shortcuts for delete and move to trash actions? I can only find how to change the default behavior of delete/move to trash, but cannot set a shortcut for the non default one. It is only available from the context menu, which is cumbersome.

You can directly delete files with "control + delete". This is a fixed shortcut. Is that good enough?

Thanks, it's just fine. Formerly it was Shift+Del and google search still gives such results, even in the krusader doc. Strange that it cannot be configured, but for me Ctrl+Del is good enough.
