Q:

Nuclide Automatic fix all eslint errors

In Atom-Nuclide for simple errors (indentation, semicolons, const etc) it appears a tooltip with a button to fix it automatically. 

This is very useful but still a bit time consuming. 
Is there a way to automate it with a command or a macro that simulates clicking on all the fix buttons? 

A:

Alt+Shift+A does what you want (default on Linux).  
The command is called "Nuclide Diagnostics: Fix all errors in current file", I found it using the command-palette.
