The Visual Studio IDE, among its myriad options and combinations and features and so forth, has a trio of rather odd key combinations:
CTRL-T – Interchanges the current letter and the one after it.
CTRL-SHIFT-T – Same thing, only for the current word.
ALT-SHIFT-T – Same thing, only for the current line.
These keybindings have been there at the very least since Visual Studio 4, where I first came across them.
And I wonder – what are they good for? Is there anyone that uses them regularly, or at all? What are they good for?
