To play Blackjack Attack using the keyboard, use the following keys during normal game play: "H" to HIT, "S" to STAND, "D" to DOUBLE, and "P" to SPLIT.
If the AUTO BET PROMPT is turned off, you can still change the bet in between hands by pressing the <SPACE BAR>.
To open any of the windows on the vertical menu bar, press <ALT> and the first letter of the menu you want to open. For example, if you wanted to quit Blackjack Attack, depress (and hold) the <ALT> key and press "Q".
Each line in the menus of the pop-up windows have one letter highlighted in red. Pressing the key that corresponds to the highlighted letter in a line selects that option. Most options are toggles that turn an option on, or off every time it is selected.
