VS Code VIM jump to file explorer like NERDTree

I am not familiar with NERDTree, but I think Ctrl+Shift+e does what you are asking in vs code. Alternatively Ctrl+p may be an alternative? You could look at linux keyboard shortcut for more reference.

The link is also available in Help > Keyboard Shortcut Reference

EDIT: I'm adding the equivalent shortcut for Mac OS since it's different layout. However, I don't use Mac OS.. So I add this without being able to confirm :

Shift+Command+E Mac OS Keyboard shortcut for VS Code

Windows keyboard shortcuts are very similar to windows ones. So, I'll just include the link to that there. Windows Keyboard shortcut for VS Code

Just my two cents:

If you are using the Vim extension for VS code you can add this to your settings.json file:

"vim.normalModeKeyBindings": [
  {
    "before" : ["<leader>","a"],
    "commands" : [
      "workbench.view.explorer"
    ]
  }
]

The exemple above uses <leader> + a while in normal mode to display the file explorer where you can navigate the file list with j and k. Pressing ENTER will open the file under the cursor and close the file list.

To set up a leader key just add in your settings.json:

"vim.leader" : "," ,
