Loop Cut and Slide Option Hotkeys

When using the loop cut and slide tool it's always a hassle to commit to the cut and only be able to change the options afterwards. So to fix this, I propose that the tool allows hotkeys to be used immediately after activating the tool. Much like with the knife tool, where it's possible to cut through the entire object by using the Z hotkey.

This is an extension to my previous proposal which could also take advantage of added hotkeys. I think the combination of these two proposals would greatly improve the modeling workflow and speed when using loop cuts.
