From the developer:
ViewFontX is a small application that allows you to see every ASCII character (in any size, font and style you select) of any installed font, and will also show what the exact keystrokes are needed to type the character. You can also print these handy tables for quick reference.
You can select one character from the Main Window to find out what key combination will give you that character from the keyboard.
