A method for configuring a keyboard for a web browser in a terminal includes analyzing a received application protocol response message; determining a key combination suitable for a selected input field based on the analysis results, if the input field for key input is selected by a user; and configuring a keyboard to include the determined key combination and displaying the configured keyboard. As a result, a keyboard suitable for an input field selected by a user may be automatically displayed, thereby preventing the user from switching the keyboard to access desired key buttons to be displayed.
