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
Using shift + v did not work for me. But just selecting the command in the help panel (with pressing ?) did what I wanted.
