There are several shortcuts which can be used to change your keyboard. If you hover your mouse over the language option in the taskbar, you will see a keyboard shortcut. However, there are generally three ways to switch between keyboard languages at lightning speed using shortcuts.
Windows key + spacebar: This is the new Windows 10 keyboard shortcut for changing between keyboard layouts. It should always work if there is more than one keyboard installed. Hold down the Windows key and then press the spacebar. You can choose between the different keyboard languages displayed by repeatedly pressing the spacebar.
ALT + SHIFT: This is the classic keyboard shortcut for changing keyboards. However, in some versions of Windows 10, this shortcut will now only give you information about which keyboard is currently active.
CTRL + SHIFT: This shortcut is an alternative to ALT + SHIFT.
If you have changed your keyboard layout, the keys may no longer correspond to the characters on your keyboard. A good example of this is the placement of the Z and Y keys on the German and English keyboards. In the German keyboard layout, the Z key is located in the middle of the top row of letters, while that is the location of the Y key on the English keyboard. This can lead to typos when entering passwords.
