I would like to remove the tab after the footnote on all of my footnotes.
Using Find/Change - GREP I can add: ~F/t. to find the footnote number followed by a tab and a space. This is in turn followed by the text of the footnote.
Is there something I can put in Change to: in order to tell it to leave the number and just take out the tab. Or maybe remove the tab and space and replace it with a space?
You're working too hard.
Just go to Type > Document Footnote Options and remove the tab separator (^t) and replace it with a space.
