Thank you Hans, I followed the manual but Scite under Linux seems to
ignore the Scintillua library, which should bring in the lpeg library.
I've installed it and added the import directive in the
SciTEGlobal.properties file, but it seems to have no effect.
Instead the customization files from the context distribution work,
because the interface is changed and the shortcut keys work.

Until now I used Geany or Texworks to edit my files, but I was curious
to try the editor you use, benefiting also from the customization you
made.
I tried to run SciTE with wine, but it's 32 bit and my Debian is 64
bit; it's possible to install it anyway, adding the i386 architecture,
but it gives some problems with package dependencies.

Sure I will not urge you to enable lpeg inside Scite, I was simply
exploring new tools to edit my files.

I've downloaded textadept, put its dir in the PATH and started
<texroot>/tex/texmf-context/context/data/textadept/context/textadept-
context.sh: it works!

Thanks again,
Massi
