Z c (
Create a new BRANCH and check it out in a new worktree at PATH.
Z m (
Move an existing worktree to a new PATH.
Z k (
Delete a worktree, defaulting to the worktree at point. The primary worktree cannot be deleted.
Z g (

If there is no worktree at point, then read one in the minibuffer. If the worktree at point is the one whose status is already being displayed in the current buffer, then show it in Dired instead.
