Well, আপনি can only do it on certain computers. On my computer, আপনি press the 'alt' button, and the '3' button at the same time, and then let go. It only works when the 3 button is on the right side of the keyboard, though. ♥ With the number pad and alt, আপনি can also make other symbols.
first : u press Start সেকেন্ড : go to programs then : go to accessories পরবর্তি : go to system tools last : go to Character map finally : look for the হৃদয় sign , press it , and press copy then u will have your heart! ♥♥♥♥♥♥♥!
