[Motion shortcuts] Add Ctrl+u for delete a whole line. #137
Description
Describe the feature or problem you'd like to solve
I think this is also standard emacs command line behaviour for terminal. Gemini cli has this feature and it is useful if you would want to re-type the whole line without waiting for backspace to finish.
Proposed solution
Add [Ctrl + u] for back deleting a line
