Problems of excessive length in figure captions

I have recently started using TEXmacs.
I have the following problem to solve: some figure captions are too long to fit into the index. Therefore I kindly ask how you practically use the caption-detailed tag, which should solve the problem.
Thank you very much.

Hello @arrigo and welcome to the TeXmacs community!

Although functional, this feature doesn’t seem to have a proper user interface yet. You can insert it by hand, though.

Type \caption-detailed inside a figure caption and press enter. The tag will be inserted and you get two fields where you can enter a long caption in the first field and a short caption in the second. Pressing enter again will activate the tag and only the long text will appear in the figure caption. The short version will be used in the list of figures.
