"bound" or "bonded"

If I use a computer command like:

bind keystroke macro

I refer to that keystroke as being bound to that macro. Is it also correct to say that they are bonded?

If I bind a bunch of twigs together, they are bound, but I don't think they are bonded.

Can "bound" and "bonded" be used interchangeably? Under what circumstances?

Bound is the past tense of bind, while bonded is the past tense of an entirely different word, bond. I don't believe I've ever met a situation where the two words could be used interchangeably.

Maybe you mean "bounded"? In any case, the answer is no:

• bound - past of to bind.
• bonded - past of to bond.
• bounded - past of to bound.

So in each case it's a different verb.

In programming, we say that the keystroke is bound to the macro, not bonded.
