Let's say I have this text:
"stringy thingy"
Is there a Textmate command or bundle that lets me place my cursor inside the quotes, press a command key sequence, and it will automatically change this pair of quotes back and forth between
"stringy thingy"
'stringy thingy'
Bonus points if there's a command or bundle that also works the same but between braces, parenthesis, and/or curly braces.
