Allow for changing of Indentation (or even all?) keyboard shortcuts

Given the addition of the Swap Lines in 0.7.4, which I have mapped to the up and down arrow keys, I would like to be able to re-map the indentation keyboard shortcuts to the left and right arrow keys to have a “joystick” for list items. Is it possible to allow for the remapping of these commands? If so, is it also possible to allow for the remapping of all commands, or as many as are possible?
