[NTG-context] hotkey and strut again

[Peter Münster]

Hello,

I'm using the following command for typesetting "hotkeys":
\def\hotkey#1{\inframed[background=screen,offset=overlay,
    height=\lineheight,corner=00]{~#1~}}
Now I realize, that with an argument without depth (\hotkey{Alt} for
example), the text is not aligned.
Same result with strut=no,yes,global.

With strut=local the text without depth is well aligned, but no more the
text *with* depth ("Space" for example). Here my test-file:

\setupcolors[state=start]
\def\Test#1{
  \def\hotkey##1{\inframed[background=screen,offset=overlay,
    height=\lineheight,corner=00,strut=#1]{~##1~}}
  strut=#1: bla \hotkey{Alt} bla \hotkey{Space} bla\blank}
\starttext
\Test{no}
\Test{yes}
\Test{global}
\Test{local}
\stoptext

Any hint is appreciated!
Cheers, Peter

P.S.: My workaround:
\def\hotkey#1{\inframed[background=screen,offset=overlay,
    height=\lineheight,corner=00]{~\vphantom{Sp}#1~}}
