The key holds the key value of the key pressed. If the value is has a printed representation it MUST be a non-empty Unicode character string conforming to the algorithm for determining the key value defined in this specification. If the value is a control key which has no printed representation it MUST be one of the key values defined in the key values set as determined by the algorithm for determining the key value. Implementations that are unable to identify a key MUST use the key value Unidentified....namespace Aspose.Svg.Dom.Events assembly Aspose.SVG IsComposing...
