Question on "back" key in \blank

Question on "back" key in \blank

[josephcanedo]

[-- Attachment #1.1: Type: text/plain, Size: 585 bytes --]

Dear list,

Sorry if question is trivial but I’d like to use « back » key in \blank to discard a \blank just before. The following MWE illustrates :

\starttext

Title.
\blank[none]
\blank[back, -line] %% I’d expect this one to discard the \blank[none] (as if it was not present)
\startalignment[broad, flushright, hanging]Right.\stopalignment

\stoptext

I’d expect that Title and Right words to be on the same line, but they are not. Did I misunderstood the meaning of ‘back’ key ? 
Thanks a lot for help and time,

Best regards

Joseph Canedo

it goes back when there's something to go back

there is also \blank[disable] to disable the next one

Thanks Hans for having replied.

My message was a bit confusing, sorry about that. I think the problem is that ‘back’ (or \blank generally) does not seem to work the same with negative blank as it does with positive blank. The following :

\showgrid\setuplayout[grid=both]
\starttext
Title.
\blank[2*line]\blank[back]\blank[line]
Line.
\stoptext

Outputs 1 blank line between Title and Line, so that \blank[2*line] is effectively ignored, as expected. But

\showgrid\setuplayout[grid=both]
\starttext
Title.
\blank[2*line]\blank[back]\blank[-line]
Line.
\stoptext

Outputs Title and Line in 2 consecutive lines (instead of being on same line). So \blank[2*lines] is effectively ignored as expected but the \blank[-line] is also ignored too. Is the latter expected or not ?

Thanks again,
Best regards

Joseph

you can't go back over non spacing but you can do this:

\blank[overlay] \strut Line.
