You question is not clear, show your code. Also the key press event is obsolete , you should be using the beforeinput event
When entering a "T" in an asp.net multi-line text box, only one <Shift> key event is caught by the onkeydown event handler of the text box.

In an ASP.NET writable multiline text box, when a "T" is entered, only a <Shift> key keydown event is caught by the text box's onkeydown event handler, and the "T" never shows up. This is running in Microsoft Edge browser. Web site is started in Visual Studio 2010.
