Thank you for replying.

I test what you suggest in Linux, it does not work. Thank you for sharing this.

In the past, it seems I did not have difficulty in getting self-adjusting <> delimiters because I found many of them in the old documents written by me.

I did not remember how I obtained those in the past. Maybe I did use the <+tabs+tabs... and I just forgot it. Maybe I was using Alt+shift+<, which, according to the general rule of texmacs, should give non-self-adjusting delimiters.

Anyway this is a minor issue, and self-adjusting <> delimiters are not very often used in practice since <> is usually not intended to be delimiters.

Finally I want to say that Texmacs is really an excellent scientific editors that makes writing mathematical documents easy, efficient, and enjoyable.

During my 11 years of using it, I wrote more than 1000 pages of documents using texmacs.

Someday I wold write a long post to summarize my 11 years of using texmacs. Thank Joris van der Hoeven and contributors of texmacs for providing a so wonderful tool.

Cheers,

Finally got it.  Press < then press Tab five times. It is hidden so deeply that I missed it.

Hi all,

In not-so-old texmacs, by default, the sizes of delimiters, such as () [], are adjusted to the _expression_ between the delimiters.
However, I found I can not obtain self-adjusting <> delimiters by any possible means I know.
I can only get small <> delimiters by using Shift+Alt+<

Could someone help?
I have been using Texmacs every day for more than 10 years. It seems I did not have this problem several years ago.
