Short cut keys in windows

In computing, a keyboard shortcut is a set of one or more keys that invoke a command in software or an operating system.
They are typically an alternate means for invoking commands that would otherwise be accessible only through a menu, a mouse, or an aspect of the user interface. These shortcuts can expedite common operations by reducing input sequences to a few keystrokes.
These shortcuts can provide an easier and quicker method of using computer programs. These commands are commonly accessed by using the Alt ket (on PC computers), command key (on Apple computers), Ctrl, and Shift in conjunction with a single letter.
These shortcuts are for the following programs and applications.
  • Word
  • Windows
  • Internet Explorer
  • File Explorer
  • Windows System Commands
  • Firefox
  • Excel
  • Mac
  • Finder
  • Chrome

How to Factory Reset Your Android Phone or Tablet When It Won’t Boot

android-recovery-mode
Safe mode can help you troubleshoot your Android, but sometimes you’ll need to wipe everything and restore your device to its factory state. But if you can’t perform a normal factory reset–say, if your phone won’t boot properly–you can do it through Android’s recovery environment.
Ensure you have any important data backed up before doing a reset. This includes your Google Authenticator credentials, which will be lost during the reset. Disable two-factor authentication on your accounts first or you’ll experience some trouble afterwards.
If safe mode doesn’t help fix your device, you can perform a hard reset by booting into a special recovery mode. First, ensure your device is fully shut down.
Press and hold the correct keys to boot the device into recovery mode. This will vary from device to device. Here are some examples:
  • Nexus 7: Volume Up + Volume Down + Power
  • Samsung Galaxy S3: Volume Up + Home + Power
  • Motorola Droid X: Home + Power
  • Devices With Camera Buttons: Volume Up + Camera
Similar devices will likely use similar key combinations. For example, the Nexus 4 also uses Volume Up + Volume Down + Power.
If your device isn’t on this list and none of the above methods work, do a Google search for the name of your device and “recovery mode” – or look in the device’s manual or support pages.
Release the buttons when the device powered on. You’ll see an image of an Android lying on its back with its chest open and its internals revealed.
android-boot-menu
Press the Volume Up and Volume Down keys to scroll through the options until you see Recovery mode on the screen.
recovery-mode-option
Press the Power button to restart into recovery mode. You’ll soon see an Android with a red triangle.
android-recovery-mode
Hold down the Power button and tap Volume Up. You’ll see the Android system recovery menu appear at the top of your screen.
android-system-recovery-menu
Select wipe data / factory reset with the volume keys and tap the Power button to activate it.
Select Yes – erase all user data with the volume buttons and tap Power. Your device will be reset to its factory state and all your data will be erased.
android-wipe-data-factory-reset
If your device freezes at any point, hold down the Power button until it restarts.


If the factory reset process doesn’t fix your problems – or doesn’t work at all – it’s likely that there’s a problem with your device’s hardware. If it’s still under warranty, you should have it fixed or replaced.
(There’s one exception to this: If you’ve been flashing custom ROMs and messing with your device’s low-level software, it’s possible that you could have overwritten the stock recovery software. In this case, it’s possible that you have a software problem and not a hardware problem.)
