In JMP13 formlua editor's tips describe below:
- Pressing Alt (Option on Macintosh) and clicking a column replaces both empty and
non-empty selected fields with that column. - The right-click menu for the Columns list has two replacement options: Replace all
occurrences of selected subexpression replaces all occurrences of the selected expression
with the currently selected column. Replace the selected subexpression with columns
replaces the selected expression with multiple columns (formerly Shift + Click) for
functions that support it (for example, Sum or Plus).
But I can understand what they mean. Somebody expaln the tips using example.
