Checking for Characters

Question:
I want to call another function only if the key pressed is a letter. Is there a way to check whether the key the user has typed is a letter (A - Z) and not any other key like space, down arrow, etc?

Answer:
Here's a script that I wrote to test the results returned when I pressed a key:



Test Script
        



    
    


I found that in Netscape, thisKey displayed 65 -90 for "A" through "Z", and 97-122 for "a" through "z". IE, however, didn't care about letter case, and displayed 65-90 for both "A" to "Z" and "a" to "z".
