roamjs-restore-back-button-alt-left.js

// restore original behavior of Alt+Left in Roam Research.
// Without this, there's not back shortcut AFAIA, which is just insane.

// USAGE: Anywhere, create a block with content {{[[roam/js]]}}.
// Place the following code nested below that block.
// Then execute the block by clicking the button.
// (this only needs to be done once; it'll be done automatically for you from now on until you stop or delete the code block)

document.addEventListener('keydown', (ev)=> {
  if (ev.altKey && ev.shiftKey==false && ev.ctrlKey==false && ev.code=='ArrowLeft') {
    window.history.back()
  }
