Ceil and floor functions in TeXmacs?

Dear Texmacs-community,
thanks for the great program. It already became my main program for brainstorming and note-keeping as I feel its much more productive than writing latex.

I wanted to know if there is a shortcut for the \lceil and \rceil (or \lfloor and \rfloor) latex commands and if there isn’t what is the easiest way for me to define a shortcut for those?


In math mode, the shortcut for ceiling function is | ` and the one for floor function is | . You can also find them in the math-mode toolbar as follows.


Usually, the corresponding shortcut shows up if you pause the cursor on the icon for a while. You can get to know most shortcuts for daily use similarly.
