Ctrl+J/K are so easy to press inadvertently

### Topic
Please consider binding moveDownCommit and moveUpCommit to something less easy to type inadvertently. Ctrl+J / Ctrl+ K are so easy to press for vim users from muscle memory and it is hard to undo if not noticed early on.

### Your thoughts
You can chose a different default binding that is harder to press and is not used for a different purpose in general. Another option is to add a confirmation prompt.

No file or test is named. Start by locating the default bindings and key-handling entry points for moveDownCommit and moveUpCommit, then review how similar confirmations are implemented. Done means the chosen safer binding or confirmation behavior is implemented and the affected interaction is covered by the relevant tests.
