Has anyone used grep styles to change 5x6 to 5×6? I tried to do it, but the dialog box to create a grep style is the character style dialog box. But, I am unable to enter a glyph. Now, I can use the find and search for \d+x\d+, but it will find 5x6 and change it all to × instead of changing the "x" only. I would hate to have to search for "x" in a document. Just trying to find a way to change "number 'x' number" to "number '×' number."
Or you can use (?<=\d)x(?=\d) [that's a look-behind/lookahead withthe x in the middle] and apply a character style to scale and shift the x. GREP styles cannot change the glyph used, only the formatting.
