You can create your own keybindings for the refactorings if you want to. The commands that the plugin registers are the following:
- On the workspace element
haskell-tools:start-serverhaskell-tools:stop-serverhaskell-tools:restart-serverhaskell-tools:check-serverhaskell-tools:undo-refactoringhaskell-tools:refactor:rename-definitionhaskell-tools:refactor:generate-signaturehaskell-tools:refactor:extract-bindinghaskell-tools:refactor:inline-bindinghaskell-tools:refactor:float-outhaskell-tools:refactor:organize-importshaskell-tools:refactor:generate-exports
- On the directories in tree view:
haskell-tools:toggle-package
