It's in the lower left corner of your keyboard, next to the Ctrl key. On many occasions it is decorated with the Windows icon; other times, it just says Win.
Many think that this key only serves to advertise a little to Microsoft and / or to open the Start menu. Well, they are wrong: it has other interesting uses.
There are a number of keyboard shortcuts (for Windows, yes) that are based on this key. Here is a list of the most common ones.
Win + R brings up the Run Window (to open documents directly by typing their name).
Win + M minimizes all windows.
Win + Shift (that arrow pointing up) + M maximizes all windows.
Win + D shows the desktop (much like Win + M)
Win + E opens Windows Explorer, starting from My Computer.
Win + F opens the window to search for files or folders.
Win + Pause (next to Print Screen) opens the System Properties window.
As you may have seen, the key is basically used to do things with windows, hence its name ( windows is window in English). Following that logic, how will you make a screen impression of what is inside a window?
Well, pressing Alt + Print Screen . A shortcut that should correspond to the unfortunate Win key, marginalized by the oblivion of many users, the very poor one. With this post we break a spear for her, and we encourage everyone to use it.
PS: For Linux users, we started a campaign for keyboard manufacturers to also put a key with a penguin 😉
