Find and Replace Variables in Calculeaf

On the Math Format tab, Find/Replace (Variables group) renames a variable everywhere it is used on this worksheet — assignments and uses. The tooltip: find and replace a variable name everywhere it’s used in this worksheet.

The Find and Replace Variable dialog with Find variable, Replace with, a match count, and Replace All. — Find & Replace Variable. The datalist lists names already on the sheet; the count updates as you type.

Rename a name

Open the Math Format tab and choose Find/Replace.
The dialog title is Find & Replace Variable.
Enter the current name in Find variable. The field has a datalist of names already on the sheet. The line under the fields shows how many occurrences match.
Enter the new name in Replace with (letters, digits, underscore — for example V_applied or sigma_max).
Choose Replace All. Calculeaf rewrites every matching region and re-evaluates. Cancel or the × closes without changing anything.

If the new name already exists, the two names merge — later assignments still win in evaluation order. The status toast reports how many regions changed.

What it does not search

This is not text find. Words in notes, headings, plot titles, list labels, and summary headers are left alone. To change those, use Find and replace text on the Text tab.

Sliders, list variable columns, sweep inputs, and plot series that reference the old name are updated with the math regions.
