- Invoke the menu as described in the section Accessing Git Branches Popup Menu.
- On the pop-up list that shows all available local and remote branches, click the desired one, and choose on the submenu.

The subsequent behavior depends on the presence of conflicts.
-
- If your working tree is not dirty, or your local changes do not conflict with the specified branch, then this branch is checked out, which is reported in a balloon in the lower-left corner of the IntelliJ IDEA window.
- If you are working with a dirty tree, and your local changes would be overwritten by checkout,
IntelliJ IDEA shows the files that prevent checking branch out, and suggests to choose between
force checkout, and smart checkout:

Force checkout: local changes will be overwritten, like git checkout -f does.
Smart checkout: IntelliJ IDEA stashes local changes, checks the branch out, and then unstashes changes back. If a conflict happens during unstash, merge dialog is shown.
