adb Key event for Keyboard next key

Issue

I have the login page as shown in the attached image. This is the native app login page.

When I try to log in, my keyboard hides the password textbox/ sign in button, so I need to click on the next key which I have marked with black circle.

I want to automate the clicking of the button.

Can anybody precisely tell me what is the key event for this key? Also I need ADB command to send this key event to the device.

Solution

adb shell input keyevent <keycode>

For the next key event, TAB is used

adb shell input keyevent 61
