: Text Style in Praat info window
As far as I know, text styles are only possible for Praat Picture and Editor windows .
Maybe, you could use some kind of special marker to highlight your matches. For example, in (a), you could use markers (b) or capital letters as in (c)
(a) He likes walking.
(b) He <likes> walking.
(c) He LIKES walking.
By the other way, I have written a plug-in for matching things in TextGrid files. Once a match is done, you can visualize, edit, extract or run scripts on those Textgrid sections. If you are interested, maybe you could take a look at it .
