In a native toolkit, TextArea supports the following key bindings as follows -

HOME - moves the caret to the beginning of the line
END - moves the caret to end of the line
CTRL + HOME - moves the caret to the beginning of the whole text
CTRL + END - moves the caret to the end of the whole text
CTRL + SHIFT + HOME - selects text from current position to beginning of the text area
CTRL + SHIFT + END - selects text from current position to end of text area
SHIFT + HOME - selects from current position to the beginning of the line
SHIFT + END - selects from current position to end of the line

The same set of key bindings are supported by AWT, Swing toolkits as well. But with JavaFX, the behavior of these key bindings are different where HOME/END moves the caret to the beginning and end of text area and CTRL + HOME/END moves the caret with respect to the lines. Same applies for SHIFT combination as well.

This might take some users by surprise since these key bindings does not match with a native equivalent on the given platform. Is there a specific reason why JavaFX is deviating from the native equivalents?

I noticed it on Soma-b30, WinXP, WinVista. I have attached a sample test for AWT, Swing and JAvaFX text areas.
