Hi,
 
How do you keep the footer buttons between the footer's top and bottom ?
 
\showframe
 
\def\myHeaderButton{\interactionbuttons[width=2cm,height=\headerheight][OK]}
\def\myFooterButton{\interactionbuttons[width=2cm,height=\footerheight][OK]}
 
\setupinteraction[state=start]
 
\setupheadertexts[text][aaa][aaa]
\setupheadertexts[margin][\myHeaderButton][\myHeaderButton]
 
\setupfootertexts[text][ppp][ppp]
\setupfootertexts[margin][\myFooterButton][\myFooterButton]
  
\starttext
test
\stoptext

Thanks,
Alan
