lost preferences after crash and can't find this line break/justification keyboard shortcut?

Looking to reassign a keyboard shortcut in illustrator which uses this text justification that I use in Indesign by typing cmnd backspace after a tab to align the next line of text to the tab area if using a soft return but can't find it anywhere since I lost my preferences. It used to just work in illustrator with the same shortcut but not now

Can anyone help please??
