Standard text editting cursor behaviour in many other products on most platforms (such as in this text box) leaves users expecting that Ctrl+Right will eventually to take them to end of the last word, before jumping to start of next paragraph.

This is a very useful feature for those without easily accessible End keys (netbooks etc) and also seems a natural exception to the 'Ctrl+Right goes to start of next text block' behaviour.  It is also useful when using with Shift key to select text a word at the time.  Selecting all white space after the paragraph is not usually the most immediate desire.

If you are having difficulty reproducing, enact without a final full stop (aka period).  This represents an unfinished paragraph.
