It can be one of the most annoying things in the world. And it can happen to the newest and shiniest of laptops or computers.
Crumps, hair, teeny tiny bits of paper; they all seem to land right in the fiddly bits of your keyboard and it's a nightmare trying to get them out.
But, if you hate the sight of it, This Morning had a handy man on the show today, giving you a life hack on how to clean your keyboard.
Steve Wilson, life hack expert, simply used a Post-it note to clean up a keyboard. The paper's sticky side is perfect for wedging in between the keys and digging out whatever is in there.
It's such a handy idea, we're actually surprised we never thought of this before.
Having shortcuts on our computers is almost as handy as having shortcuts in real life.
But how handy would it be if we could make our own shortcuts? Well, now you can.
What you might not have known is that you can create shortcuts for most Windows programs that you might have installed. It's actually been built into Windows for a while now so if you're using Windows 7, 8, 8.1 or 10, you can activate this.
All you need to do is find the program you want to create a shortcut for and simply right-click it (this can be in program files or on the desktop icon itself) and then click on properties.
Next, click on the shortcut tab and you will see the shortcut key entry in the middle. Shortcut combinations always start with Ctrl + Alt so all you have to do now is choose the third key.
Once you have chosen your desired key, hit apply and you'll be able to open the program by hitting those buttons!
And if you want to reset it, press Shift, Ctrl + Alt and it will return to normal.
Easy peasy? We think so.
