Hi,

Thank you very much! In fact, you can simplify further: the Alt+R before | is
not necessary. This is due to the machinery of TeXmacs to detect
automatically pair of delimiters.

Best,
Frank

Hi Frank,
another option is to type "^L . q ^R |" in math mode
^L . creates a pair of invisible brackets
^R | replaces the invisible closing bracket with a (closing) vertical bar.
with macOS look and feel, ^ = option

Hi,

I wonder what is the correct way to do that? For the moment, I only know that
I can write the thing in the absolute value then delete the first delimiter,
which is a bit more difficult since I need to move the cursor back and forth.

Best wishes,
Frank

Hi Frank,
I use a right-hand-side-only delimiter for this purpose.
(math (concat (around* "<nobracket>" "q" "|") (rsub "C") "=y"))

Dear all,

I wonder how to input the symbol for restriction of function? Now I input,
say,

(math (concat "q|" (rsub "C") "=y"))

which will generate, in my opinion, an incorrect spacing (see the space before and
after "="). I also suspect that this is semantically incorrect.

Best wishes,
Frank
