Does Enter key trigger a click event?

Question

In the code below removeSelectedCountry() should be called when a span element is clicked and handleKeyDown($event) should be called when there is a keydown event on a div.

@Component({
    selector: "wng-country-picker",
    template: `
    <ul class="CountryPicker-selected" *ngIf="selectedCountries.length > 0">
    <li *ngFor="let country of selectedCountries">
        <span class="Pill Pill--primary" (click)="removeSelectedCountry(country)">
        {{ country.name }}
        </span>
    </li>
    </ul> 
    <div (keydown)="handleKeyDown($event)" class="CountryPicker-input"></div>
`,
providers: [CUSTOM_VALUE_ACCESSOR]
})

But removeSelectedCountry() is called every time Enter key is pressed.

To make the code work, I had to change the click event to mousedown event. It works fine now.

Can anyone explain why the Enter key would trigger the click event?

@Component({
    selector: "wng-country-picker",
    template: `
    <ul class="CountryPicker-selected" *ngIf="selectedCountries.length > 0">
    <li *ngFor="let country of selectedCountries">
        <span class="Pill Pill--primary" (mousedown)="removeSelectedCountry(country)">
        {{ country.name }}
        </span>
    </li>
    </ul> 
    <div (keydown)="handleKeyDown($event)" class="CountryPicker-input"></div>
`,
providers: [CUSTOM_VALUE_ACCESSOR]
})

Adding class snipppet:

export class CountryPickerComponent {

private selectedCountries: CountrySummary[] = new Array();

private removeSelectedCountry(country: CountrySummary){
    // check if the country exists and remove from selectedCountries
    if (this.selectedCountries.filter(ctry => ctry.code === country.code).length > 0)
    {
        var index = this.selectedCountries.indexOf(country);
        this.selectedCountries.splice(index, 1);
        this.selectedCountryCodes.splice(index, 1);
    }
}

private handleKeyDown(event: any)
{
    if (event.keyCode == 13)
    {
       // action
    }
    else if (event.keyCode == 40)
    {
        // action
    }  
    else if (event.keyCode == 38)
    {
        // action
    }    
}

For ENTER key, why not use (keyup.enter):

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="values=box.value">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  values = '';
}
