With the aim of reducing mouse activity i was wondering if there was such a command shortcut (eg CLS or Ctrl+L) to provide the SQL*Plus (?) "CLEAR SCREEN" command functionality found by clicking the rubber-on-end-of-pencil icon in Oracle SQL Developer to clear the lower "Results" sub-tab (...incorrect terminology i'm sure).
To clear the SQL window you can use:
clear screen;
which can also be shortened to
cl scr;
If you're using sqlplus in a shell, like bash you can run the shell's clear command from sqlplus:
SQL> host clear
you can abbreviate of course:
SQL> ho clear
SQL>Clear Screen (It is used the Clear The Screen FUlly in SQL Plus Window)
Use cl scr
on the Sql* command line tool to clear all the matter on the screen.
CTRL+D? http://www.scribd.com/doc/7580088/SQL-Developer-Hot-Keys
If that doesn't work, you might be able to set up an Accelerator: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b31695/intro.htm#sthref208
Ctrl+Shift+D, but you have to put focus on the script output panel first...which you can do via the KB.
Run script.
Alt+PgDn - puts you in Script Output panel.
Ctrl+Shift+D - clears panel.
Alt+PgUp - puts you back in editor panel.
Use the following command to clear screen in sqlplus.
SQL > clear scr
In the Oracle SQL-plus:
shift+del
