Characters input method

A method for inputting characters is provided to simplify an operation for inputting the characters in an address window of a web browser or a search window of a website by using only the mouse, and enable a user not memorizing a keyboard to input the characters easily. A character input window(100) including character buttons(110) and a finish button(120) for inputting a character input finish signal is displayed near a word input window(16) in a pull-down mode when a user moves a mouse cursor(30) to the word input window of a web browser or a website. The character corresponding to the clicked character button is inputted to the word input window when the user clicks the character button. A driving signal for driving a search engine linked with the word input window is generated by using the characters inputted to the word input window as search data when the user clicks the finish button. The character input window is disappeared when the user moves the mouse cursor to a position excluding the word input window and the character input window.
