Is there a way to set modal property keyboard=true for all modals within the page?

I am trying to set the value keyboard=true for all modals within a page. Is there a way to configure that to be set as default or do I need to go to each modal and set it?

I know the case is closed and you've rendered your verdict, but I wanna testify:

The accepted answer sets the keyboard option for all the modals that currently exist by going through them one by one^†. You can extend objects that have not yet been created, and do so while taking less of a performance hit by just setting the default option:

$.fn.modal.Constructor.DEFAULTS.keyboard = true;

Demo in Fiddle

^† - Here is a direct quote from the documentation:

$('#myModal').modal({ keyboard: false })   // initialized with no keyboard

This code initializes each modal in the selector $('#myModal') and also sets one of the options when doing so.

Here's a demo with two modals - they both will be initialized immediately! It goes through each one, initializes it, and applies the setting. The question was not asking for a way to initialize the modals that use a setting. It was asking for a way to default the settings so future initializations wouldn't have to specify it. In terms of performance, just doing the the lookup in the DOM for $('.modal') costs extra that overriding the default does not.
