Hello,

I am still fiddling with it: for the path of the file, I would like to 
use find-file, since it searches in several directories (i.e. first 
locally, then a repository of pdf files...). But 
<find-file|path1|path2|<merge|key|.pdf>> gives me a url like

file:///home/qoptik/Literatur/Simon1994a.pdf

which acroread doesn't like. So my current problem is getting substring 
to work in order to strip file:// (7 characters) out of find-files' output:

  <action|stripme|(display (substring (get-env "var") 7 9))>

TeXmacs complains in the terminal:

  <unnamed port>:1:10: In procedure substring in expression (substring
  (get-env "var") 2 ...):
  <unnamed port>:1:10: Argument 2 out of range: 2


[Afterwards I would substitute '9' with (string-lenght (get-var "var")) 
or, better (string-length s) if I manage to (let s (get-var "var")), 
which I don't, in the body of the action, prior to the (system... ) call.]


Thank you very much for your help!
