Lookup value
The Lookup value block finds a value in a table of keys and values. It compares the value you give it, like {{message.content}}, with the key of each row and returns the value of the first row that matches. Use it instead of a condition with a branch for every key when each branch would do the same thing with a different text, then use {{result('lookup_id')}} in a single block after it.
Rows match when the value equals the key, contains it, or starts with it, depending on the match mode. Turn on ignore case to match Hello with hello. Keys and values can use placeholders, and you can paste many rows at once as key = value lines or two columns copied from a spreadsheet.
When no row matches, the result is the default value, or empty if there is none. Check for an empty result with a comparison condition to handle that case.
