Is there a good method to zoom in and out in Chrome with PAD?

I want to be able to zoom out 50% in Chrome at the start and then at the end zoom back in. I could use send keys and Ctrl + '-' repeatedly and at the end send keys Ctrl + '+' but it seems not the greatest solution. Because if the flow fails when its zoomed out the flow would need to always also need to check if Chrome is zoomed out before using send keys Ctrl + '-'.
