Hi everyone,
I never know that inside of the _KeyPress(Ascii&) it's possible to grab CTRL+A,+V,+C, etc.. // Select All, Copy, Paste etc... has predefined ASCII values. It's 1, 2, 23, 26 and there are a lot more. 
I always garbed CTRL+A,+V,+C by _KeyDown(), or _KeyUp().
A small test. Here I suppress keys from the keyboard can be used to insert invisible control code into a text box.
But "select all, copy, paste, undo" now works well.
