I'm using dakboard kiosk on raspberry pi and is there way to code a GPIO button as "F5" keyboard input for refresh?

I made a wall calander by using old monitor and raspberry pi and dakboard like a kiosk. sometimes i need to refresh the web page and i use my keyboard F5 button to do that. but i was wondering is there a way to use push button in GPIO to work as a "F5" button for refresh my web page? I used this code to make it autorun

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

@xset s off
@xset -dpms
@xest s noblank
@chromium-browser --noerrdialogs --incognito --kiosk http://dakboard.com
