Many people know the shortcut for 'select all': Control + A.
This is far faster than fiddling with each filter manually. So, if you have a multiple filters active, you can 'reset' all filters by using the shortcut twice in a row: once to remove the filters (which clears all filters), and once again to add a new autofilter. But the best part is toggling off the autofilter will clear any filters that have been set. With the same shortcut, Control + Shift + L (Mac: Command + Shift + F) you can toggle filters on and off any list or data set. If you frequently filter lists or tables, this shortcut should be at the top of your list. But did you know that you can also paste formatting, paste column widths, multiply and add values in place, and even transpose tables? It's all there. At the very least, you probably already use paste special to strip out unwanted formatting and formulas (Paste special > Values).
There are so many things you can do with paste special it's a topic in itself. At that point, you'll need to chose the type of paste you want to perform. This shortcut, Control + Alt + V (Mac: Control + Command + V) doesn't actually finish the paste it just opens the Paste Special dialog box.
