how to trigger function if customer just starts typing

Issue

I've been looking around, and I can't find an answer to this. I would like to have a mat dialog box open when a customer just starts typing. No focus nor input. Just starts typing. I'm sure the answer is simple, but I just can't find it. Thanks in advance!

Solution

A simple host listener should do the trick:

@HostListener('window:keyup', ['$event'])
  keyEvent(event: KeyboardEvent) {
      this.openDialog();
  }

Where openDialog is the function that triggers your MatDialog.
