Fill and Randomize Buttons - SafetyFlux/captchalogue GitHub Wiki
The fill buttons, shown as green squares with the "<" symbol inside, allow the user to fill in the entire code at once, rather than altering individual symbols. This dialog box pops up when the button is pressed.
If the user input isn't eight characters long or any invalid characters are included in the code, an error message will pop up and you'll be allowed to re-enter a code.
The randomize buttons are shown as yellow squares with the letter "R" inside for the alchemy cards and as a yellow rectangle with "RAND" inside for the main card. Each button randomizes the corresponding code.
