My default key-bindings for pasting are
{ \"keys\": [\"ctrl+v\"], \"command\": \"paste\" }, { \"keys\": [\"ctrl+shift+v\"], \"command\": \"paste_and_indent\"
Check out the FindKeyConflicts plugin. There are several options for looking at all key bindings, or just conflicting ones, in a variety of contexts. All the options are available via the Command Palette.
