#5238: Lack of 'Send' button breaks tablet input use-case

 It's been well-established (though still controversial) that a send button
 is fairly redundant for typical keyboard/mouse input.  However, when using
 handwriting recognition to input text on a touchscreen, pressing Enter is
 completely inconvenient.  Right-clicking and selecting 'Send' is only
 slightly less inconvenient, due to the awkwardness of the right-click for
 many types of pen-based input.

 The obvious use-case for handwriting recognition on touchscreens is to
 complete the text-entry and then tap a widget to send the text.  Previous
 release notes say that the 'send' button is supposed to display when a
 keyboard is not available.  Unfortunately, on tablet PCs one cannot
 disconnect the keyboard, so the 'send' button will never appear, despite
 the keyboard being inaccessible at times.

 I suggest either adding a configuration option to enable a send button or
 creating a plugin that does the same.
