Bash's vim mode, not vi - bash

I was fascinated when I discovered vi-like bash's editing mode. One can easily toggle it by issuing set -o vi command. But is there any way to toggle vim-like mode?
I mean when you are in a vi-like mode you can press v key and edit your commands in a fully functional vi editor's window but I would like to know how to force bash to start vim editor instead of vi because of the perks vim provides us (visual selection, additional commands etc)?

If you set EDITOR variable, in bash you can press Ctrl-x ctrl-e to edit your current command line in your EDITOR e.g. vim
EDIT
the ctrl-x ctrl-e is for emacs mode commandline editing, which is the default one. If you have already set it to vi mode, you could do what you have said, pressing the v. If you want to open the cmd line in vim, you have to set the EDITOR variable (in your .bashrc for example)
Personally I edit command line in emacs mode, even though vim is my main (and only) editor.

In your .bashrc, put the following line:
export VISUAL=/usr/bin/vim
If you want vim in many other contexts too, such as in git, you should also set EDITOR:
export EDITOR=/usr/bin/vim

Ctrl-P doesn't work on vi mode of command line editing on mac terminal

https://www.gnu.org/software/bash/manual/html_node/Readline-vi-Mode.html
said we could do set -o vi to use vi mode instead of emacs mode for command line editing.
And the help: ex-edit-index sais
c_CTRL-P CTRL-P after using 'wildchar' with multiple matches:
go to previous match, otherwise: recall older
command-line from history.
However when I press CTRL-P I just got ^P
May I know why ?
Readline's "vi mode" is neither vi nor Vim. It is a partial emulation of vi shoehorned into the command line context.
That <C-p> you are referring to is a Vim command so there is no reason whatsoever to expect it to do anything in that context. Vim's documentation is totally irrelevant in this case.
Search for Vim Mode bindings in $ man readline for the actual bindings at your disposal in that "mode".

Paste bash command, but make sure it doesn't run

Sometimes when you ctrl-v with bash it will run the command even though you didn't intend to run it yet - is there a way to paste a command into the bash shell / terminal making sure you don't actually run any of the command(s)?
if you could set what was on the terminal prompt programmatically, you could do this with bash on MacOS:
export BASH_PROMPT="$(pbpaste)"
which ties into my other question that I just asked:
How to change the value that's in the prompt
There is a Readline variable:
enable-bracketed-paste
When set to On, Readline will configure the terminal in a way that will enable it to insert each paste into the editing buffer as a single string of characters, instead of treating each character as if it had been read from the keyboard. This can prevent pasted characters from being interpreted as editing commands. The default is off.
To turn this on, put something like
set enable-bracketed-paste on
into your ~/.inputrc.
This was introduced in Bash 4.4 / Readline 7.0.
Use ^X^E aka Ctrl+X Ctrl+E in bash to open your $EDITOR for command entry.
Paste and/or edit as much as you want, across as many lines as you want. When you're done, save and exit, and bash will run it.
(In vi mode, the shortcut is v)

Syntax highlighting in bash while typing commands

Is there a way to highlight my input into the bash console while typing code?
For example, if I use bash keywords, those are highlighted in a specific color?
edit:
I'm particularly interested in solutions which make use of what bash already has to offer, like tweaking .bash_profile or similar.
You can use the syntax highlighting feature of vim/vi.
Open a file, for example open existing file called file.sh, enter
vi file.sh
Now press ESC key, type “: syntax on” i.e. type as follows
:syntax on
To turn it back off, press ESC key, type : syntax off
:syntax off
To make it permanent you can create a new .vimrc file in your home directory. Open the terminal and enter:
vim ~/.vimrc
There you can enter your various configurations. When done, you need to save the file and restart vim.
To be sure which vimrc is being used, you can ask inside of vim by typing:
:echo $MYVIMRC

How do I get out of ESC mode in zsh?

When using zsh, I sometimes accidentally press Escape out of habit, expecting it to clear the entire line as it does in Windows. Instead, it goes into a mode that I'm not sure how to get out of. The cursor goes back one character, and some keys perform some special commands, but all I really want to do is get out of this mode and be able to press Ctrl+U to clear the line.
Searching around has been tough - I get results for escaping characters.
Short answer: press a.
Medium answer: press a, then enter bindkey -e.
Long answer: Like a lot of UNIX shells, zsh has an emacs-like mode and a vi-like mode. You're in vi-like mode, and ESC takes you out of the vi-like insert mode. a puts you back into insert mode, with the cursor after the current character. (Sorry for the two different uses of "mode," but it is the accepted terminology in both cases.)
bindkey -e overrides the settings from the rc files and puts zsh into emacs mode, which only has one mode (i.e., no "ESC mode"), so this won't bother you any more. Unfortunately, it won't carry over to your next shell invocation. bindkey -v would switch from emacs mode back to vi mode.
In the absence of any other configuration, zsh defaults to emacs mode, so unless there's something in one of the rc files, the likely culprit is that the EDITOR variable is some form of vi, which causes zsh to default to vi mode. If you don't like vi mode, then you should probably hunt down what part of the system-wide or user-specific configuration is causing zsh to default to vi mode and turn it off by removing it or overriding it in one of those rc files.
If everything else fails, when you're in ESC mode, type :w then Enter to save, and then :q to exit. You can also type :wq and Enter

How do I open a file in Vim from inside a Conque shell

Often I find my self navigating the filesystem from a Conque shell in Vim and want to open a specific file inside my existing MacVim session. Is this possible ? - I was hoping for something like:
shell> open some/file.txt
and then have file.txt pop up inside my existing Vim window (preferably in a new tab).
Note: I am using #wycats vim dot files (not sure this matters).
Type from ConqueShell
mvim --remote-tab-silent filename
This will open the file in a new tab in MacVim
You could also write a Bash alias to shorten the command (assuming you are using bash).
Put in your ~/.profile
alias vim='mvim --remote-tab-silent'
this would enable you to type
vim filename
from ConqueShell or bash, and have it open in a new MacVim tab, rather than terminal vim. It of course does disable your ability to run standard vim (although you could still use the vi command), so maybe you would want to name the alias differently.
Just to add, this will work only if you placed the mvim executable on your path E.G. /usr/bin/mvim. It comes with the MacVim.app

The beauty of running a shell from inside vim is you have all of vim and the shell at your disposal.
gf is your friend. Once you get the file you want displayed on the screen in some way, you can enter normal mode, move the cursor to the file you want to edit, then use the gf command to navigate to the file. There are many ways to use this. Any program or command that outputs file names is great for this (ll, git status, etc). You could also type the filename into the shell, just to make it visible on the screen without actually running any terminal commands (tab completion is handy here).
It is possible, you can start vim as server and then add as many files as you want, but I'm not very familiar with this, so I can't give you just a direction.
