Keyboard shortcut for "to the power of" (exponent) signs?

Question

Is there a keyboard shortcut for "to the power of" signs?

Example: ²

Answer 1

You can use specific set of UTF-8 characters for entering sub/super scripts. Process is simple:

1. Hit Ctrl+Shift+U
2. Type out 00b2 ( that's zero-zero-b-2)
3. Hit space or Enter key and you will have a superscript for power 2.

Like this ². Of course you will have to substitute appropriate utf character code for other subscripts
