Thank you! I did find a slapdash work around, by having two different lines of text, using the wait and no-wait functions {w=} {nw}. One line has a word with the glitch tag, the other has no glitch. When played together, the first line of text appears normal, delayed for a second, then swaps to the next line when it hits the word with the glitch effect.
Makes it look like the text gets deleted and replaced with a brief glitch effect as it happens. It looks exactly like I wanted and It wouldn't have worked without your code! Thank you.
