Hi Jean:

FYI, the following behavior is implemented in my working copy of Hyperbole
but not yet released anywhere.  It will be in the next test release.  Using
what is described below together with globally labeled/named implicit
buttons, you can create in-buffer, parameterized Action Buttons that you
can invoke from anywhere by name or by pressing the Action Key on them.  I
hope this will meet the bulk of your needs and be easy to use.

------
From the DEMO file:

** Action Buttons

A new feature of Hyperbole is a universal syntax for creating implicit
buttons of any existing type, known as Action Buttons.  Such buttons are
delimited by angle brackets, < > and come in three forms:

  1. action type invocations - these begin with an action type name (from
the
     list displayed by {C-h h d t a RET}) and are followed by any needed
     arguments to form the action, e.g.

          <link-to-file-line "${hyperb:dir}/hact.el" 40>

  2. function calls - these are similar to action type invocations but begin
     with an Elisp function name rather than an action type name, e.g.

          <find-file-other-window "/tmp">

  3. variable displays - these consist of just an Elisp variable name and
     display a message with the variable name and value, e.g.

          <fill-column>

Since implicit buttons can be labeled with a name and placed in the global
button file for invocation by name, you can give short names to any such
buttons you want to invoke frequently.

An Action Button is recognized only if the first name within the angle
brackets is an existing action type or Elisp symbol.  Otherwise, other
implicit button types will be tested and may activate instead.

With Action Buttons you need not remember any special syntax for each type
of
implicit button.  You can freely embed them in any type of text and use the
Action and Assist keys on them as you do with any other type of implicit
button.
