When using computers, we often need to switch between full-width characters and half-width characters to meet different input needs. In order to improve efficiency, we can set shortcut keys for full-width and half-width switching to facilitate quick switching of character modes. This article will introduce how to set the full-width and half-width switching shortcut keys and some tips in practical applications. In the Windows operating system, we can set the shortcut key for full-width and half-width switching by following the following steps: Open the Control Panel, click the "Time Zone and Language" option; find "Change Keyboard or Other Input Methods"
