The Comment Toggle Trick

This trick below can be used to toggle between two sets of code, with one symbol in the code with no additional short-keys to learn, and no tool dependencies!

//* /*
someCode(); someCode();
/*/ /*/
someOtherCode(); someOtherCode();
//*/ //*/

Here is a version for simply commenting code in and out:

//*
someCode();
//*/

Deactivated / commented out:

/*
someCode();
//*/
