I frequently need to type in some matrices, and the menu command Insert>Table/Matrix>New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert>Table/Matrix>New..., preferably using only mathematica? Thanks!

  • $\begingroup$ If you just use the keyboard shortcut for Add Row or Add Column it will create a new matrix, but not pull up the dialog box. edit I see that isn't what you are looking for $\endgroup$

  • $\begingroup$ @JasonB Yes, I'm aware of that. I can programmatically do the fill all and fill diagonal function in the dialogue box, but the lines between the rows and columns are really nice for my needs and I can not reproduce that without clicking the menu item. $\endgroup$ Commented Feb 2, 2016 at 11:10

    $\begingroup$ The token seems to be "CreateGridBoxDialog" $\endgroup$

In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line

MenuItem["&New...", "CreateGridBoxDialog"]

to read

MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers->{"Control"}]]

and now I have the keyboard shortcut

enter image description here

But maybe it is safer to change the KeyEventTranslations.tr file, since now that I've done this I can't get the singlelaunch option to work any more - fixed via restart.

  • $\begingroup$ It fixed via a restart so no worries. That is a real pain for linux, if you don't use that every time you double click a notebook it opens a new instance of Mathematica. $\endgroup$
