The mouse connected to your PC or laptop comes in handy for executing a lot of commands and sometimes the keyboard is used just to type. The keyboard isn’t just a glorified typewriter as there are a lot of shortcuts that you can use from your keyboard to boost productivity and save time.

Here are 10 such keyboard shortcuts that you should definitely use:

1. Alt + Tab: Switch between open items

If you have too many software and apps open on your desktop, this keyboard shortcut allows you to quickly jump from one to another by showing them all to you in the centre of the screen. You can directly hop onto the one you want to switch to next.

2. Ctrl + Shift + Esc: Open Task Manager

If your system has become slow or momentarily hung, and you need to find out which program is the culprit, this shortcut can help. It will allow you to directly access the Task Manager and find out which is the program that is not responding. Just end that task and carry on.

3. Shift + Delete: Delete the selected item without moving it to the Recycle Bin first

While deleting a file from your system, if you are sure that you will not change your mind about the item you are planning to delete, then you can save space by directly permanently trash it by using this command.

4. Windows key + L: Lock your PC

This shortcut will let you lock your computer instantly. In case you have to even leave your system for a minute you must lock it before you go. One shouldn’t leave the system unlocked to prevent others from accessing files or other information on it.

5. Ctrl + F4: Close the active document

This keyboard shortcut is used to close the active Window and comes in especially handy in case there are multiple windows of the same software open. Rather than shutting them down one by one, simply use this shortcut.

6. Ctrl + Y: Redo an action

While almost all of us know that the command to undo an action is Ctrl+Z – and one of the handiest features – there is also a command to redo an action. To redo an action, simply use Ctrl + Y.

7. Ctrl + Shift with an arrow key: Select a block of text

This command is useful when you use your system for reading and evaluating text either on the internet or in a document that you have saved on your file. All you need to do is select the first word and you can then use the arrow keys (Up, Down, Left, Right) to move in the direction to select the desired text.

8. Windows key + D: Display and hide the desktop

If a lot of your work involves switching to and fro from the desktop, then this option will be the best thing to use. By using this shortcut, you can escape the entire process of minimizing all the windows that are already open to reach the desktop.

9. Windows key + I: Open Settings

The settings of your system are buried deep in the control panel. However, this shortcut lets you directly access the Settings. This programme includes all the basic things such as display settings, account settings, Network settings, devices you have added and so on.

10. Windows key + number: Start the app pinned to the taskbar in the position indicated by the number

If you are in the habit of pinning the apps and software that you use on your taskbar this option will let you directly open it (or switch to it if the app is already running). For instance, if calculator is pinned as the fourth app on your taskbar then windows logo key plus 4 will open calculator or move to that in case it is already open.
