Ctrl movement support in commit message input

**Is your feature request related to a problem? Please describe.**
When I'm writing a commit message and change my mind (totally not because I made a typo or anything), I'm forced to delete part of the content of the input by pressing backspace like a caveman.

**Describe the solution you'd like**
It would be an absolute blast, if we could use ctrl to navigate faster, for example:
- ctrl + 'left arrow' could jump to the beginning of the previous word
- ctrl + 'right arrow' could jump to the next word ending
- ctrl + 'backspace' could delete to the previous word beginning
- ctrl + 'delete' could delete to the next word ending

**Describe alternatives you've considered**
Nothing. To be honest, I'm not a very smart man.

**Additional context**
Rhinos are cool.
