Button1->Caption = "&&abc";
일듯..

To underline a character in a Caption that appears on the button, include an ampersand (&) before the character. This type of character is called an accelerator character. The user can then select the button by pressing Alt while typing the underlined character. To display an ampersand character in the caption, use two ampersands (&&).
