Add support for find and replace regex patterns
Per user request:
We do a lot of edits where the speaker has been misidentified. The usual format is to have the speaker ID at the start of the line followed by a colon. Right now we select the speaker with a double click and then hit a snippet key. It would be nice to be able to assign a speaker to the current line (or even multiple lines) without having to do the select. Allowing find/replace with a regex pattern, which could then to be assignable as a hotkey, would be perfect.
