Extjs listener on keystroke checking if its ANY character <p>I cant seem to find this anywhere. I want to find the best way to check whether a keystroke is actually a character. </p> <pre><code>listeners:{ 'keyup':function(f, e){ //Is key a letter/character } } </code></pre> <p>EDIT</p> <p>Thanks to everyone who has answered, I DO know how to detect the actual key that was pressed, I want to know how to detect whether the key is actually a character (not arrows, backspace, enter etc) </p>
