Added hotkeys for pasting and disabling, and a settings dialog.
DragKing does exactly what you say it will do (no surprise). But it's
not quite what I'm looking for. On re-reading the posts I realize I
mis-stated what I wanted.
I don't want highlighted text automatically copied to the clipboard.
What I want is a mousebutton action that will copy already highlighted
text (as opposed to right-click, then click "copy" on the context
menu, or as opposed to Ctrl-c). So I'd want a setting category for
"Copy", not only for "Paste".
What would really be slick would be to include rocker gestures (left
click while holding down the right button or right click while holding
down the left button). I would then assign right rocker to copy and
left rocker to paste.
