Basic "macro" functionality

I have been playing around with macros in 0xDBE, but haven't yet figured out how to make them work in a simple and convenient way.  Let's say I have this very simple (dummy) Postgres query:

 
SELECT d.datname, ts.spcname
FROM pg_database d
JOIN pg_tablespace ts
     ON ts.oid = d.dattablespace
LIMIT 100;

In tools like pgAdmin or SQL Server Management Studio, it is trivial to map keyboard bindings such that I could highlight one of the table names (e.g. pg_database), hit a keyboard shortcut, and automatically see the first 100 rows in the table, view the table definition, or whatever other useful information I care to bind.

As an explicit example, I have the following binding in pgAdmin:

Ctrl-4 => "SELECT * FROM $SELECTION$ LIMIT 100;"

Pressing Ctrl-4 then automatically executes "SELECT * FROM pg_database LIMIT 100;" against the current connection, shows the results, and does not require me to modify the query text or perform any additional typing.  This is extremely powerful, especially given that one can write and bind arbitrarily complex stored procedures to these mappings, which is much simpler than recording and maintaining a long macro of keyboard actions (like I was able to find in 0xDBE right now).  

Is there a way to do this in 0xDBE?  Or is there somehwere I should submit this post as a new feature request?  The functionality described above is something I often use hundreds of times per day in other editors, so it would be great functionality to be able to use within 0xDBE.

Thanks!
