In LyX, if I go to the insert delimiters menu, I can insert a norm. Is there way to attach a shortcut to this?

By norm, I am referring to the double bar on each side.

  1. Go to Preferences > Editing > Shortcuts.
  2. Click on "New".
  3. Under "Function", enter "math-delim Vert Vert" (note the capital V's).
  4. Click on the blank rectangle and then use the key combination that you want for a shortcut.
  5. Click OK.
  6. Click Apply.

In general, to find the function that you need to enter, use LyX with debug mode. If you are using Ubuntu, one way to do this is to run "lyx -dbg action" instead of "lyx". Now, all of the functions will be printed to the terminal. So when you go to the insert delimiters menu and click on the norm delimiters, the terminal will give you the function that is being run.

The expression "math-delim | |" also works. Actually it has already been assigned the shortcut Alt-M | in my LyX version. – e-birk Jan 31 at 16:58
@e-birk That is useful as well. I think both notations are common for the norm. I was under the impression that the user wanted double bars on each side. – scottkosty Jan 31 at 19:57
True, the number of bars was not specified and I was only thinking of one bar. "math-delim Vert Vert" gives double bars while "math-delim | |" gives single bars. – e-birk Feb 2 at 10:51
