BoCaps

什么是 BoCaps？

BoCaps lets you switch selected text between uppercase and lowercase with a double-tap of Caps Lock, in any Windows app. No menus, no shortcuts to memorize. Works in Word, email, browsers, code editors, and anywhere else you type. Runs quietly from the system tray, starts with Windows, and lets you adjust the double-tap speed to match your typing rhythm. Free to use, with an optional way to support the developer.
