Keyboard Shortcuts aside first, my biggest pet peeve right now is not being able to press Enter to move on to the next word when using CTRL+F function in the Overlay Browser. Having Keyboard Shortcut is also a blessing, I've been using the Overlay function extensively ever since Valve first implemented the Note function and the lack of this keyboard functionality is a bit jarring. Sure I can just not use Steam Overlay and alt-tab or just use my phone, but that's besides the point.
