Question: I seek an editor where `Ctrl`+`C` copies, `Ctrl`+`X` cuts, `Ctrl`+`V` pastes, `Ctrl`+`Z` undos, `Ctrl`+`Y` redos, `F3` searches and `F2` renames. When I click the left mouse button, the cursor should go there. All modes should be active at the same time (command and insert and ...).

Also `Ctrl`+`W` closes the current tab in tabbed interfaces, `Alt`+`F4` closes the currently focused app, `Ctrl`+`Tab` tabs between guess what, tabs, `Ctrl`+`O` brings up open dialog, `Ctrl`+`P` brings up print dialog,

What Linux editor exists out there that can be used in the terminal and has that behavior?

Answer: 
What are "universal shortcuts"? There is something like a "universe" but there are no "universal shortcuts". It is a subjective term. Many vim users will consider the vim shortcuts "universal" and do everything to change different keybindings to resemble these of Vim.

The keyboard shortcuts you mention resemble these that are quite common in graphical environments. There is a terminal based text editor, [micro](https://micro-editor.github.io/), that implements this style of shortcuts. It is available as a Snap in the software center of Ubuntu. At least in Ubuntu 19.04, it is also available as an APT package.
Mine. I wrote a text editor exactly for this reason. Unfortunately I don't have a ready-made installer but as long as you have Tcl installed (and optionally Tk for clipboard support) you should be able to use it. It's just a single file of code: <https://github.com/slebetman/tcled>

Just place the `tcled` file somewhere in your `$PATH` and make it executable by doing `chmod +x`.

If you don't like my editor there's also slap which is quite nice: <https://github.com/slap-editor/slap>. It tries to implement a terminal editor that feels like [sublime](https://www.sublimetext.com/).

Unlike my editor you can easily install **slap** via npm (you need node.js installed of course):

```
sudo npm install -g slap

```

Honestly I would recommend using **slap** but I could not resist plugging my own software . The number of users for **tcled** is around a dozen (mostly people who need a better editor than plain vi on routers and embedded devices - because almost all installs of Linux come with tcl pre-installed so installing my editor is just copying a single text file).
