Is there a way to make bash use visual selections for text replacement?
Standard text input conventions don't work:
- If you press Shift+Left Arrow, the character to the left should be visually selected
- If you press Ctrl+Left Arrow, the cursor should move to the beginning of the previous word
- If you press Shift+Ctrl+Left Arrow, the word to the left should be visually selected
- If you visually select some text then press any key, the text should be replaced with the text of the key you press
Vi mode (set -o vi) visual selection conventions don't work:
- If you enter normal mode, press 'v' to enter visual selection, then press 'h', it should visually select the character to the left
- If you enter normal mode, press 'v' to enter visual selection, then press 'B', it should visually select the word to the left
- If you visually select some text and then press 'R', it should erase the text and leave you typing the replacement

this guy did it for zsh:
I've made a VI VISUAL Mode for !ZSH. Emulates !VIM 's visual mode "v" in the cmd-line. http://bazaar.launchpad.net/~raybuntu/%2Bjunk/ZSH_stuff/annotate/head%3A/zle_vi_visual.zsh
it's awesome!

When I want to do this in ZSH I use edit-command-line. You can add the following into your .zshrc:
autoload -U edit-command-line
zle -N edit-command-line
bindkey -M vicmd v edit-command-line
Then I can just type v in command mode and it will open up my $EDITOR. You can do the same thing in Bash by just typing v in command mode without any customization.
