Formatting text

[elguapo]

How do I SPEED UP the changing of text color and other characteristics? In a page of text, I want to change the color, then make BOLD, every 2nd, sometimes 3rd, line of text... without messing with the ones in between. This means I have to triple-click the line of text, then turn change the color, then turn it bold. Doing this to 12 or so lines on a page makes it take a minute or two. I'd rather simply position the cursor, then call up a script (e.g., Cmd-4), but I can't see how to do this in a script, though I've looked and looked. Any clues for this non-programmer? Many thanks in advance...

Try something like:

Set Selection [ Start Position: Position ( Get ( ActiveFieldContents ) ; ¶ ; Get ( ActiveSelectionStart ) ; - 1 ) + 1; End Position: 

Position ( Get ( ActiveFieldContents ) & ¶ ; ¶ ; Get ( ActiveSelectionStart ) ; 1 ) ] 

# 

Insert Calculated Result [ TextColor ( TextStyleAdd ( Middle ( Get ( ActiveFieldContents ) ; Get ( ActiveSelectionStart ) ; Get ( ActiveSelectionSize ) ) ; 

Bold ) ; RGB ( 220 ; 0 ; 0 ) ) ]
