improve manage staging area keyboard shortcuts
i reformatted the code of a whole project, which changed a 100 files or so. when i wanted to browse quickly the changes i could not find keyboard shortcuts to navigate the changes. go to next file, page down in a file, add to the staging area, remove from staging area.
not so intuitive i found:
- space adds a file to the staging area, pressing again space does not remove it.
- could not page down the diff view without mouse. pgdn goes down the file tree.
- then i tried vi or emacs shortcuts. but, typing a letter opens a search window but does not find anything.
