How do I globally replace a bold character override in FM10?

This is far as I've managed …

1. apply the character style in question to a word, then use Edit > Copy special to put the character style in the clipboard
2. use Find/change to locate Character format override
3. if this finds a local override you want to clean up, click [Change & find]

Not global in the sense "sort out my whole book with one click", but perhaps a step in the right direction.

Off-thread question: what's the general feeling about formatting for step 3 – is it OK to be informal and start an instruction with "if"? I like to explain the condition before giving the instruction, to avoid tripping up people like me who tend to process strictly from left to right :-} An indented paragraph after step 2 "If … then continue to step 3" would be thorough, but seems a bit clumsy.
