The "select next element" editor action is almost identical to "widen selection" in IntelliJ IDEA but IDEA's
implementation has a couple of differences that improve its usability. In IDEA if the action is invoked with no
selection then the current word is selected regardless of the context. In NetBeans the current structural element is
selected. This makes a difference in string literals where IDEA initially selects the current word, then the whole
string on the second invocation, followed by the whole string including quotes on the third. NetBeans immediately
selects the whole string including quotes which is a lot less useful.

Also in Ruby when assigning to the return value of an "if" statement this action immediately selects the whole block
when invoked on the variable name. It would be a lot more useful and natural to initially select just the variable name
and only expand to the block on the second invocation.

When selecting the previous element NetBeans never returns to having no selection - however many times you invoke it the
minimum selection is the whole structural element where the caret was when "select next" was first invoked. IDEA's
implementation will return the editor to its inital state - no selection and the caret returned to its original position.
