Keyboard shortcuts not only make your digital life a little more streamlined and efficient, they're incredibly convenient for maneuvering on the go. I have a few favorites that I use frequently (where would I be without Fn+F11?), but I know there are tons more that I'm not aware of. Enter Keyonary, an online dictionary of keyboard shortcuts for Mac.
Using the search bar, type in the action you'd like your shortcut to perform. Keyonary will return applicable shortcut results. In addition to a huge database of keyboard shortcuts, they make it easy to add glyphs to any text; just click on the "glyphs" tab in the upper right corner, and select the symbol you're looking for. Keyonary will copy them and add them to your clipboard. Then, just paste them into the text:(☮ ♥ ☺)!
