KEY PREVIEW

The key preview tool provides two ways to discover key codes. Pressing a key or a combination of keys on the keyboard will cause the associated codes to display in the top area of the key preview dialog. SHIFT, CTRL, and ALT key combinations are also designated.

The bottom area contains tables for Virtual Key Codes and ASCII key codes.

VK CODES

VK codes point to a key on the keyboard. The VK code for a lower case letter and its upper case equivalent are identical, because they are typed on the same keyboard key.

ASCII CODES

The ASCII code refers to the character that will be displayed onscreen, so a lower case and upper case letter will have different ascii codes.

ASCII CHART

Click the button to call up a separate chart of printable characters. Click on a character with the mouse, or scroll through the list with the arrow keys. The currently selected character is zoomed in the display area on the lower right.
