Better approch is use alt+right and alt+left keys to navigate like Jetbrains IDE Webstorm does
Here is my config. it also include create new file and folder
{
"key": "ctrl+n",
"command": "explorer.newFile"
},
{
"key": "ctrl+shift+n",
"command": "explorer.newFolder"
},
{
"key": "alt+left",
"command": "workbench.action.previousEditor"
},
{
"key": "alt+right",
"command": "workbench.action.nextEditor"
}
