This function replaces the most recent occurrence of oldText with newText in active dictation. Active dictation contains all phrases dictated since the last command, possibly separated by pauses.

CopyCapitalize a word in a recently-spoken phrase

Cap <_vocolaDictation> = Dictation.ReplaceInActiveText($1, String.Capitalize($1));

If you said "The town public library (pause) is excellent", and then "Cap public library", you would see "The town Public Library is excellent".

The special variable <_vocolaDictation> matches any series of words in active dictation. Those words are then capitalized using Capitalize, and both the original and capitalized versions are passed to ReplaceInActiveText.
