Yup - https://livecode.com/resources/api/#livecode_script/tabalign

I added it in LiveCode 7 because we needed most of its mechanisms to
implement right-to-left text properly; getting per-tab-cell alignment
was just a happy bonus ;)

By necessity, tabs have to apply to a whole line - it doesn't really make sense 
to have them settable at any other granularity. (Though, as always, you can set 
them on the field as a whole).

Re: fontNames

I'm currently fiddling around with fonts. I see that the list returned 
by 'the fontNames' contains some 'placeholder' values, namely these:


   (Default)
   (Menu)
   (Message)
   (Styled Text)
   (System)
   (Text)
   (Tooltip)

Is there a way to find out what font is used when a field's textFont 
is set to "(Default)" or some other placeholder value?
Yes and no - the font that is being used for, say, "(Message)" has a 
name that will be returned if you ask the macOS system for the font for 
push buttons and then ask what the name of that font is - it might be 
"San Francisco" on recent versions of macOS, for example. When I 
originally added these pseudo-fonts in LC8, that's exactly what asking 
for 'the effective textfont of...' would give you. Unfortunately, it 
turns out that the font you get when you try to request the macOS system 
fonts by name is *not* the same font as when you ask the 'official' way 
(which means that setting the textFont of a control to its effective 
textFont actually changes the font!).


So, no, because LiveCode doesn't provide a way to get the "display name" 
of the font used for these.


But yes, because the font really *is* "(Message)" because that's the 
only name for it that LiveCode can actually use.


I hope that's about as clear as mud for you ;)
