I'm writing this because I found it harder than expected, but actually is super easy.
- From the "Commit" panel (or the "Branches" panel) focus on a commit an press Shift + c, you can select more than one
- Go to the "Commit" panel (in the "Branches" panel it doesn't work) and press Shift + v, will ask for confirmation.
- DONE
NOTE
On older versions, you simply had to press c and v without Shift
Thanks !
