Hello - Im looking for solution to this problem:

If [text style of selection = X ] then A else B.

There does not seem to be an obvious way to get text style of selection. So I tried this workaround:

If ( TextStyleAdd ( Middle ( Get ( ActiveFieldContents ) ; Get ( ActiveSelectionStart ) ; Get ( ActiveSelectionSize ) ) ; HighlightYellow ) ; "1"; "0")

thinking that if the selection is styled as in the TextStyleAdd expression then it would evaluate as TRUE but it doesn't work.

Is there any way?

Thanks.

This is a trick question, because a selection can have multiple styles, and each substring within the selection can have a different combination of styles.

The two functions that can provide the answer are GetAsCSS() and GetAsSVG(). Both return the input text split into SPAN elements according to the style/s applied to each substring. If any substring of text is formatted as HighlightYellow, then both GetAsCSS ( text ) and GetAsSVG ( text ) will contain the pattern:

background-color: #FFFF00;
