Branch, Merge & Rebase - Commit+

Branch

Cmd+Shift+B creates a new branch from the current HEAD. Switch branches from the sidebar or via Quick Search (Cmd+Shift+F).

Merge

Drag a branch onto the current branch to merge it. Alternatively use Cmd+Shift+M to open the merge flow directly.

Rebase

Hold ⌥ while dragging a branch onto the current branch to rebase onto it instead of merging.

Interactive rebase

Commit+ is designed to grow toward direct history editing, including reorder, squash, and fixup workflows. Those drag-based interactive rebase actions are roadmap items, not shipped behavior in the current docs.
