My browser window (Safari) always gets zoomed in and I always forget the key command to reset it. So this post is mainly a reminder for myself. If you happen to come across this post and it helps you then great! Thanks for reading my post.
On most all of the latest version of Browsers ( Chrome, Safari, Firefox and Opera) on Mac OS X is simple to reset.
If you do a key combo of ?(command key) + 0 (zero key) that should reset your browser zoom level back to 100%.
