Binding keyup or keydown events in Angular is pretty straight forward.

<input type= "textbox" (keydown)="onKeydown($event)" >

onKeydown ( $event ){ console . log ( $event . key ); // This will log key which is pressed. }

But most of the time we need to bind some specific key. For example backspace key.

Here is one way of doing it, which indeed everybody does.

onKeydown ( $event ){ if ( $event . key == ' Backspace ' ){ console . log ( ' Backspace pressed ' ); } }

This works fine but here is a better way in Angular to do the job.

Here is how you bind keyup or keydown event to some specific key in Angular.

<input type= "textbox" (keydown.backspace)="onBackspaceKeydown($event)" >

onBackspaceKeydown ( $event ){ console . log ( ' Backspace pressed ' ); }

This is much simpler and cleaner way.

But what if you want to bind keyup or keydown event to some key combination?

For that you combine keys togther to trigger the event only when the key combination is triggered.

Here is how you bind control + z key combination to keydown event.
