This is great Robert, thank you.

Myself I am thinking in terms of HyperScope as envisioned by Doug
Engelbart, so in the mean time I have started building a system.

My system is based on the database.

Do you think that I can bind .hypb file to certain key which is not a
file?

For example I have database table hlinks with hlinks_id and I would
like to bind .hypb maybe also as a string to the hlinks_text database
field.

Is there such function already in Hyperbole, to tell "where is the
.hypb" file? I could place it temporarily maybe in any directory and
then after usage delete it automatically.

Does that exist?

Jean

> A new feature of Hyperbole is a universal syntax for creating implicit

> 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
