Section "using vi-mode in your shell" is incomplete

[emk2203]

For the use of vi-mode, it's necessary to also add to your .inputrc:

set show-mode-in-prompt on
set vi-cmd-mode-string "\1\e[2 q\2"
set vi-ins-mode-string "\1\e[6 q\2"
set keymap vi-insert
"\C-L": clear-screen

Otherwise, you won't have any indication of what mode you are in, which makes it impractical to use vi-mode.

The last line is an example of how to carry over keybindings which you want to keep from the EMACS mode.

Besides set -o vi, the .bashrc file should also reset the different cursors:

# set vi mode for command line:
set -o vi

# reset cursor after manipulations, like for vi mode above
PS0="\e[2 q\2"

This gives a smooth and user-friendly vi-mode experience.
