Question for keyboard shortcuts on Product Hunt

Hi PH, I've take a quick search and haven't found if Product Hunt has shortcuts built in. For example, V to Upvote, G to Get It, M to Comment. I browse my RSS reader daily and jump to the specific product directly (also from RSS reader browser shortcut). Sometimes I take a quick look and think the product deserve an upvote but I'm lazy to move my hand off keyboard to reach the mouse. Surely I or someone can make personal userscript to make shortcuts work in my/their browser, but it would be great if PH makers can consider to have it built-in. Let's make a poll and see if people do have same thoughts
