I checked the settings of compare plugin and there was no mention of it capturing any keyboard shortcut. That is bad ethics. They should have mentioned their keyboard shortcuts and should allow users to change of disable that.
Well, you are right, it should be mentioned, but most of Notepad++ flies sort of lightly on the documentation, so…
After installing any plugin, you can go to the Shortcut Mapper and see what keycombos you loved for something else have been hijaaked.
