The Key Bindings menu allows you to specify the keyboard shortcuts you use for everything from compiling a document to cutting text to resetting the Interactions Pane. The only restriction is that the shortcut you choose must be one basic entry--for example, you cannot use Ctrl-X, Ctrl-S to save a file, but you could use Ctrl-Alt-S. However, actions accept multiple key bindings so that a user may bind both Ctrl-X and Ctrl-S to the save file action and use either keystroke combination to save their file. Adding support for a wider range of keyboard shortcuts is a feature request currently under review.
