I know that "Alt + J" toggles the clean 2 lines function but is there a keyboard shortcut that just takes you to the clean menu with all options?
The short answer is yes.
The stock shortcut is:
J^51#^
There is probably a direct, extended code that would do it, but this would also work:
J^·^È^;^F9^
BTW, the "·^È^" portion of this is not required -- it is leftover from the old days, with slow computers, to keep the menus from "flashing". The J is the letter you want to use, the ; semicolon chaged to the Edit menu, and the F9 opens the Cleanup menu. The ^ carats separate the commands -- quite simple, really.
