How to write at the rate in computer?
Here's a trick most people don't know: If your @ key isn't working properly, you can copy-paste it from somewhere else, or use the Character Map on Windows (search for it in Start Menu) or Character Viewer on Mac (press Control+Command+Space). Another method is to hold Alt and type 0064 on the numeric keypad (make sure Num Lock is on). This works in most applications. If you're regularly switching between different keyboard layouts (like bilingual typing), I'd recommend installing a keyboard layout switcher app that shows you which keys produce which characters in your current layout.
The "@" symbol (at the rate) is super easy to type once you know the keyboard shortcuts:On Windows: Hold Shift + 2 on the main keyboard (not numpad) Or Alt + 64 on the numpadOn Mac: Shift + 2 on most keyboard layoutsOn Mobile: It's usually on the first symbols screen (press the "?123" or "sym" key)The method depends on your keyboard layout. For US keyboards**, it's definitely Shift+2. For some UK or international keyboards, it might be different. If Shift+2 gives you " instead of @, you might need to change your keyboard layout in system settings to US International.
