Tracing the Logical Key...Forms5.0

Question

Hello friends,
Here is a problem with me that I have tried and
tried but didn't achieve. Please:
Q: I need a to write a function which will tell the
last logical key pressed. ie: if I press enter/NEXT KEY
etc..then the function should trap that and should display in a
display item on the forms.
----- like
FUNCTION GET_CMD()
RETURN VARCHAR2 IS
BEGIN
END;
Thanks a lot for the valuable time that U have taken for this.

So, I've recently taken over a few DB servers.  One of the servers (we'll call it TEST), if I ps -ef oracle|grep pmon, I find 2 running processes, GREEN and BLUE.
OK - on to my client's TNSNAMES.ORA
TEST_GREEN=(DESCRIPTION=
        (ADDRESS=(PROTOCOL=TCP)(HOST=IP_FOR_TEST_SERVER)(PORT=1521))
        (CONNECT_DATA=(SID=RED)))
TEST_BLUE=(DESCRIPTION=
        (ADDRESS=(PROTOCOL=TCP)(HOST=IP_FOR_TEST_SERVER)(PORT=1521))
        (CONNECT_DATA=(SID=ORANGE)))
Note, that the SIDs in the tnsnames do not match the running PMON processes.
So, I thought, let's look at the listener.ora, as you can see - the SID in the listener matches the SID of the TNSNAMEs.  But, my question is - how does the listener push a connection bound for RED to a process running as GREEN and an ORANGE to BLUE? PLEASE HELP!  Here it is the listener.ora:
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = RED49.FQDN)
      (ORACLE_HOME = /u03/oracle/product/11.2.0.3)
      (SID_NAME = RED)
    (SID_DESC =
      (GLOBAL_DBNAME = ORANGE49.FQDN)
      (ORACLE_HOME = /u03/oracle/product/11.2.0.3)
      (SID_NAME = ORANGE)
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY=RED))
        (ADDRESS = (PROTOCOL = IPC)(KEY=ORANGE))
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
        (ADDRESS = (PROTOCOL = TCP)(HOST = FQDN_OF_DB_SERVER)(PORT = 1521))
        (ADDRESS = (PROTOCOL = TCP)(HOST = IP_FOR_TEST_SERVER)(PORT = 1521))
Use of "(CONNECT_DATA=(SID=ORANGE)" in tnsnames is deprecated, in favor of "(CONNECT_DATA=(SERVICE_NAME=ORANGE)"
Show us the output of 'lsnrctl status'
In that output, observe the difference and relationship between 'service" and 'sid'
