My progamming key bindings

I like the idea of editing of VIM, but I still think this is not the best. Some keys of vscode, emacs and particularly Kakoune ans helix are modern.

General idea

Editors

I current use vscode for its light-weight and extensions. I use the extension Dance - Helix Alpha and EasyMotion to simulate Helix's key bindings.

Also, I add some key bindings:

// Place your key bindings in this file to override the defaultsauto[]
[
    {
        "key": "Escape",
        "command": "dance.modes.set.normal",
        "when": "editorTextFocus"
    },
    {
        "key": "ctrl+w",
        "command": "vscode-easymotion.jumpToWord",
        "when": "editorTextFocus && dance.mode == 'insert'"
    },
    {
        "key": "=",
        "command": "editor.action.formatDocument",
        "when": "editorTextFocus && dance.mode == 'normal'"    
    },
    {
        "key": "Ctrl+[",
        "command": "workbench.action.navigateBack",
        "when": "editorTextFocus && dance.mode == 'normal'"
    },
    {
        "key": "Ctrl+]",
        "command": "workbench.action.navigateForward",
        "when": "editorTextFocus && dance.mode == 'normal'"
    }
